I just bought a pair of those super white blueish headlight bulbs (H4) and I think I got something now thats a bit too much in wattage. They are rated 100-120 Watts. I also got a set for the fog lights and they are (H3) 100watts.

Will they do any harm? I got them last minute as this guy was selling them for a good price so didnt have the chance to research. They work great and look like the car has Xenons.

i remenber reading a post by larry bible where he said if you go over the recommended wattage the excess heat could melt the adjuster housing, if you are looking for xenon style, go with the sylvania silver star light bulbs. i have them in all my cars

bulb comparison

My freind has those Silverstars....not a big deal and dont look like xenons. I want that blue tint to the lighting like the ones I got offer but im just panicking now about the wattage.

I did take the covers off behind the bulbs for added cooling if that helps.

if you uses the bulbs you have they will melt the reflectors, i have driven next to mercedes with xenons and theses are similar in their clarity,

Ill have at look at the silverstars but the problem is I cant return the ones I bought!

thats what happens when you buy before researching. the sylvannia silverstarts ST are the whitest that they have. but if you want a blue look to it then get the Sylvannia CB which stands for cool blue. piaa also makes great bulbs but the life span is shorter than the sylvannia ones

The wiring harness and combination switch is not made for that load. Make sure you have glass lenses and metal reflector, otherwise it may melt.

Insert a 12V relay close to the headlight (one each for low and high beam in each side), and draw a separate 4 square mm from 12V supply to the relay contacts in each side. Use original wiring from combination switch to energize the relays, and connect the lamps to the switched 12V supply.
