Just wanted to pass this along:

2003-2005 Mercury Grand Marquis Fog Light - Replacement, FO2594102, Without wiring harness, Direct fit - JCWhitney

Just saved about 100$ on a new foglight by getting one from a grand marquis. (Rosenthal wants 170ish, dealers want like 300, other parts sellers want like 180)

 

did you actually install these and they're 100% plug and play?

 

I actually installed this, and they're the same unit.

I personally ran a ~1/16th bigger drill bit through each of the four mounting holes for easier installation though.

 

Nice. Ok cool thanks for the heads up.

Reason I ask is because dopple tried the same thing in my fog light thread (off a focus or something) and reported back that despite looking almost identical, the measurements were just a bit off enough for them to not work.

 

Oh, one more thing.

I said 01+ in the thread title.

Rosenthal indicates that the part was changed in 2004, I'm not sure if this will work on an 04-05.

 

btw I have some OEM 01's for sale for only $50....Just FYI to anyone looking for some
