I currently run the Hella E-codes for which I paid about $90. This FM group buy price is attractive enough that I might just pick up a set for spares. Glass lenses on my other vehicles seem to pick up stone chips every few years and with the Miata being fairly low-slung I'm bound to need them sooner or later.

In the last pic with HIDs/E-codes, is it just overexposed or is the light pattern really that blobby? The upwards flares look much more vertical and intense with HIDs than with H4 bulbs, which could be blinding to other cars.

I'm happy with my H4/E-codes but more light on the road never hurts. I was thinking about picking up a set of HIDs (probably 6000K, nothing too ricey) to try in my same housings but I don't want to be "that guy" driving around with the fucked up blinding aftermarket headlights.

My Hella e-code/HID's definitely don't have as much upward glare as that last pic shows.

Now, that beam pattern doesn't look too unreasonable.

worse case: you add a line of electrical tape to the bottom edge of the lens. I personally think the typical bulb oem cheap H4 bulb with those lenses is enough, but when others use the better hella bulbs they look great. i see no need for HIDs.

Yeah that looks very similar to mine. I have my lights aimed correctly with 6000K bi-xenons and have never been flashed for blinding oncoming drivers.

Default Watts?

At what wattage would a wiring upgrade be necessary?

No real set number. Some people say the wiring is too small for any kind of upgrade, but lots of people have run double the wattage with no issue. My 100's have been doing just fine with no problems yet after well over a year. Don't know if I would want to go with the really high wattage bulbs (I think 140 is available) mostly out of reliability. 140W bulb won't last very long most likely.

I got mine in, waiting to be able to walk so I can install them. Kinda pointless though as I won't be driving my miata for a while.
