My old high beam bulbs were 65 watts too.


Hmm, I doubt a 80W bulb would work in there huh
You can always try!

*Caution*
Dont go to big on the wattage with stock wiring. The general was tight on sizing the wire gauge......from 55W to 80W thats a 32% increase in amps and the wire may burn up............I had a problem a few years back with a dodge minivan, didnt burn up the van but melted the harness and blew the fuse.

higher wattage just draws more power from the battery, but 5 isnt a lot

What we have to keep in mind here is that many of the aftermarket "HID" lamps are not really a higher wattage. They use the xenon plasma gas to increase the brightness with the same power used. Most of the times, the wattage given is "equivalent" wattage. A stock Sylvania 9006 bulb could be either 51 or 55w. The replacement "HID" might say that it is 80W, but is really only using 55w or so.

As far as the wiring goes, 18ga wire is good for 14 amps and 16ga wire is good for 18 amps. Even two 80w bulbs is a little over 13 amps.

If you decide to go nuts, you will want to add relays and larger wire to feed the lamps.

Thats true. But there are some bulbs that are actual 80w draw, and then their are other that are 55w draw but are as bright as a 80w bulb. Thats what some people over look and that when the run into problems. BUt also they change the degrees it burns. I believe stock is around 2500, Silverstars are 4000, and if you go 6000 which is the brightest pure white. anything above that and youll start getting a blueish tint to them and hurt the lighting output.
