I did some searching on the replacement of driving lights for the CL-S, and saw that PIAA bulbs were a close match to the HID headlights. Are the PIAA's a direct plug-in for the factory bulbs (meaning no modification necessary to the bulb receptacle or wiring harness)?

I was thinking of going with these:

 

I used these and they were nice

After LED's:

 

But he doesnt want modification seymore ?
I thought these are slightly too big the ones you used ?

 

I replaced all my corner bulbs with PIAA xtreme white LED bulbs and they match my HID's perfectly

 

These were the 15 LED bulb that I ordered and they fit right in to the standard housing...


I then ordered the 18 LED bulbs which required me to alter the road light housings

 

how about these. This is where I order all my HID products, both drop in and replacement Kits
