T-700 headlight bulbs

If they are like the T660 bulbs they are xenon hid and they cost about $130 and you can only get them from the dealer

 

H11 55 watt is what I pulled out of my T700 and I replaced it with the same bulb. Cost me roughly $20 for a pair about 3 months ago from a Petro.

 

The HIDs were optional... ours run halogen. The 700s used the same headlamp assembly as the 660 and 440.

 

what would happen if you replaced the 55 watt with 100 watt bulbs?

 

Did that on my Audi A6 and it helped a lot. However it should be noted that the headlight assemblies on that car have a cut-off shield in place, similar to that of HID's, to eliminate glare for oncoming drivers (in fact, the assemblies on that model A6 and the UrS6, which has HID's, are the same). As far as I can tell, the T700 halogen assemblies do not have any glare shielding so 100 watt bulbs would probably result in excess glare.

 

putting in 100 watt bulbs will work but would be like running high beams all the time. you would not be a very popular person except to law enforcement.
