SMT LED Brake Lamps
Curious to know if anyone has tried the newer style SMT type LEDs for brake lamp bulbs? If you've tried em, please share your experience. Thx

Got a link?

plenty of sources

Someday, and I bet it won't be too far off, led's are going to completely replace incandescent's in cars and the price will plummet. Same goes for light bulbs for the home.
This guy did a nice writeup, and I dig those square led's. http://www.maushammer.com/systems/ta...l%20Light.html http://www.maushammer.com/systems/tail-light/index.html C |
The taillight on my Ducati kept burning out from the vibration with aftermarket exhaust, so I replaced it with a 48-led 1157 replacement. The incandescent bulbs would last less than an hour, but the led bulb has lasted over a year so far. It was like $80, so it better last.
I also have 3 Watt amber 1157 LED's in my front turn signals which I am happy with so far. I got mine from www.superbrightleds.com though it looks like they discontinued my monster 48-led bulb EDIT: I'm an idiot, mine aren't surface mount |
All the bulbs on my MS6 are SMD LEDs except the rear brake and blinker lights.. Haven't gotten around to those yet. Got all mine from V-LED, and like them a lot.
|
hmmmmm those v-led things are quite nice... wonder how those would look. Dunno if i want to be the $80 guinea pig.
*goes back to check their customer satisfaction guarantee* |
Alot of the IS300 crowd was doing LED lights using straight up diodes wired as a group.
http://mmsport.s5.com/is300/LED/brandonbaz/IMG_0530.JPG Basically they are just drilling out the inside lens and replacing it w/ a set of LEDs ...looks nice at night if done right. This fool used halos.. he''s the same guy that makes the flush mounted miata lights. (AAC) Not my style, but different. http://my.is/forums/attachments/f90/...d-dsc03657.jpg |
Standard diodes won't light up the reflector, and won't be seen from off center.
I'm looking for a lamp that will illuminate the reflector like an incandescent, but has the quick response time as the LED. This is for safety, not for ricer boy LED appearance. When I'm in rush hour traffic, I always notice how much faster the LED lamps illuminate on a car that has a combination of standard and LED brake bulbs. |
*cough* rice *cough*
holy hell its dusty in here. |
LEDs have a lower power consumption per bulb than incandescent, but has anybody done the math to see if a given LED array draws less power?

When I'm in rush hour traffic, I always notice how much faster the LED lamps illuminate on a car that has a combination of standard and LED brake bulbs. There is a few LEDs on that www.superbrightleds.com link that have rearward/outward shining LEDs to reflect off the reflector. I will try these as soon as I remove the bulbs & turnsignals from the Miata and get the bulb # off them. I also want them solely for safety reasons. Paul always says he can't see my turnsignals with these altezza style taillights. |
Good point, and very easy to prove/disprove, but not the direction I'm going for with this thread. If anybody has the calculations or at least a source where I can get the numbers myself, could you shoot me a pm? Thanks |
Oh, I just remembered, my dad's Passat has SMT LED taillights, they look a lot like that IS300, but much brighter. They work very well.
|
Tim, those are still typically not too good for off directional viewing.
If you use standard type bulbs in your tail lights, they are stop/tail 1157 turn 1156 reverse 1156 center brake 921 license plate 89 |
Now im really curious to try the ones on v-led that look like a frikken christmas tree...

Sorry Ben, not trying to hijack your thread, but I do seem to have a power draw issue at night with my flush mounted headlights, running lights, and gauges lit up. It's even a bit more nocticeable whne I turn the blinkers on. If LEDs put out as much light as incandescents, but draw less power, that might help.
If anybody has the calculations or at least a source where I can get the numbers myself, could you shoot me a pm? Thanks Your alternator doesn't do much at idle As far as power consumption goes, it's very easy to figure out... but start a new thread mkay. We can walk you through it. |
I went ahead and got some coming from VLEDs. If anyone else wants some use coupon code CLUBLEX for 10% off ;)

Ben,
Do you think in order to add the super-dooper-blind-everyone 48-led turn signal bulbs, our Miatas will require adding in the resistor to make sure they don't blink like a goddamn rave party? |

adding a resistor = ghey
the right way to do it is to get a LED capable flash module |

I would assume this is park of the packaging. This appears to be a replacement for the normal bulb.

LED brake/tail lamps will not flash with thermal flasher units due to their extremely low current draw. Some cars indicate this by increasing the flash rate of the turn signals, some do not flash at all. This can be remedied with load resistors wired across the turn signal bulbs to simulate a filament bulb load. One way to test this is to pull out one of your blinker bulbs. If you get a bulb out warning or rapid flashing, you will need load resistors.
Load Resistor Kits: 6 Ohm, 50 Watt resistors can be connected across the turn signal wire to simulate the load of a regular filament bulb (2 Amp load). This will solve LED related turn signal problems such as hyper flashing, no flashing or burnt out bulb indications. One resistor is required for each turn signal bulb. Kit includes two resistors and 4 gel filled moisture resistant splice taps. Connection Instructions: Using the included splice taps, connect one wire to ground and the other wire to the turn signal wire. You do not have to cut your car's wires. Squeeze splice taps with pliers. One Load Resistor required for each turn signal bulb. No instructions are include with these kits. ELECTRONIC LED FLASHERS This problem may also be remedied with an electronic flasher, these units are not available for all makes of vehicles. Many vehicles have two blinker units, one for hazard and one for turn, so locate both by sound output. It is not always necessary to replace the hazard flasher. |

also led brake lights are calculated to have a certain degree of safety to them because they light faster than a filament bulb, this might sounds ridiculous but it's true, it's why you see them on factory cars now not because of cost

Got them in and installed.
The SMT LED bulb assembly works pretty much how I figured it would. It has the "fill" of about 90% of the stock incandescent. It's about 90% as bright at non center angles. At the "hot spots" directly behind the bulb, light output is brighter, more concentrated, and deeper red. Now for the real good news: The reaction time is dramatically better. It's not a small, trivial difference as the specs would lead you to believe. The LED is on and fully bright before the incandescent is even beginning to light up. That was the benefit I was going for. Because sometimes a half second can make all the difference. I'm also going to order a set in amber for the rear turns. The instant on, instant off of the LED is much more attention grabbing than the stock bulb. There's a reason why police light bars use em. |
Knew you'd like em, mang! :bigtu:
I'm still trying to find someone that'll give me some altezzas so I can attempt to disassemble them and build an LED array then flat black the entire inside of the case. No luck yet. |
Pics!!!

Or, you can take a voltage regulator and make it into a current regulator. I've done this before with a LM317T. I forget what all you do
http://img248.imageshack.us/img248/1398/lm317regsp1.gif Assuming VREF = 1.25, then ILIMIT = 1.25/R1. So if you wanted 100ma, then R1 = 12.5 ohms. R1 will be dissipating some power, so be sure that it's rated appropriately. But if you're just using this purely to sink enough current to ground to make the flasher relay happy, then it's kinda pointless. Regardless of whether you use an LM317-based circuit or just a resistor, the same amount of heat is gonna get generated. |

Right. At night. Put the led's on one side and the standard bulbs on the other. Etc.
I'm probably going to try the cheaper ones from superbrightleds instead of the surface mount leds Ben tried...unless he posts good pics or video. |
if you want to "disperse" the leds light a little better and reduces its narrow beam of outputted light
a quick rub with some sandpaper on the led will do the trick |
I took a camera phone video with a standard bulb in one side and the LED in the other. It came out shitty, but good enough to get the point across. Then youtube denied my upload for "duplicate content" or some such shit. :confused:
Mike, you're welcome to pop by and record it with yall's bad ass camera. I'd recommend the surface mount, but would not recommend the regular LEDs, especially for altezza style housings. One of these days (weeks, months, years), I think I'll gut the high mount stop lamp (3rd lamp) and add some LEDs to it too. I was also thinking of adding some red LEDs to the side mount lamps, behind the reverse lenses, as my tail lamps. |
I'll take you up on that Ben.... maybe swing by the hizzouce at lunch and then drop by there on my way home so it'll be a bit darker outside.
|
which side is stock :dunno: ;) |
wow, that's really noticable. LED on the drivers side, it looks like your lights are doing the wave with the lag between them.
|
Ben, there is one of the LED 3rd brake lights on m.net classifieds:
http://www.miata.net/cgi-bin/isc/cla...evaction=today |
Hey Ben, Did you get red or white LEDs for that? I like how crisp the drivers is vs the fuzzy passenger illumination..

I just ordered a set of fancy amber turn signal bulbs for the rear of the miata. I just love the instant on and instant off the LEDs provide when I see them on others' cars. I'm thinking about trying them in my MB too, but that thing has a fairly sophisticated bulb out warning system that displays on the dash (though not nearly as sophisticated as the new ones that will shift a blown lamp's function to the next best non blown lamp :)), so I'm kind of hesitant. http://a763.g.akamai.net/7/763/1644/...img0-2/img.jpg |
I've got 3 watt led front turn signals that I'm happy with. Also, my dad's BMW motorcycle automatically uses the brake lamp at a lower voltage if the tail lamp burns out.
|
the orange 1156 base SMTs are nothing short of fantastic.
|
From the video they look pretty damn bright. Especially when the hazards are on by themselves. Where can one get these bulbs? I am googling now, but wanted to know if you guys have a specific place you would get them.
Vash- |
I replaced all of my indicator lights on my Audi with LED's about 4 years ago with the cheapo unidirectional autozone LEDs, best $80 i ever spent, i haven't drove my Audi in about a year because of *cough*
http://a368.ac-images.myspacecdn.com...8c1920cc2f.jpg so i dont have any pics or vid of it, but for some reason they don't blink extra rapidly or anything aside from the normal instant on instant off sexiness and are extremely bright even tho it just looks like uber-bright glowing orbs as they are only outward firing, bleh |
they look awesome ben, I'm slowing changing all of mine to smt led as well. My busted superbright led DRLs were just changed to smt.

Yeah it is v-leds.com
I priced out a complete set for my car, about $85 all together. front and rear blinkers, brake/tail lights, and the third brake light. Based on a quick search on ebay and froogle it looks like these guys are about the only source for this style? Scratch that... here is another source http://www.ledlight.com/detail.aspx?ID=196 Anyone try this style? More light output and half the price. Not SMT, but... http://www.ledlight.com/detail.aspx?ID=158 |

My mom got me those for my birthday. They sent 1156 bulbs instead of 1157, even though the box matched the part no. on the site. When she emailed them about it, they said they had to check with their engineers and investigate the problem. :bang:

Looks really good man! So I take it you're using the resistors you bought from Fry's?
