I have heard a lot about the voltage boosters for the stock lights. what exactly do you get from these? Is it brighter, whiter lights? Can a Sylvania Silverstar bulb be used in conjunction with the kit? And where exactly can I find such a boost kit? Thanks

What am I? The eBay salesman?
I guess I am , since I got my D1 on eBay. :lol:
Expect twice the light output, half the bulb life, and BOY can you see! Any down side: expect shorter bulb life and the boosters will draw more current but nothing you should worry about. Also expect hash on the AM radio reception.
If in doubt,about burning up your headlight wiring, order the cheap ($25-$50)H4 upgrade wiring harness so your lights have a new direct path to the battery. The lights will then look factory bright. Imagine that then with the voltage boosters.
The only way you know you got the boosters is when you turn them on for the first time cold, the lights turn on then after a half second they get BRIGHT. My kit came with 110/140w replacement bulbs but I will wait until I upgrade the wiring harness first.
I am still using my original bulbs and they are burning white not yellow as in the original stock. I bought legal yellow Eurolights to complete the upgrade but the originals are still burning so why bother to change it?
Use the stock cheapie bulbs first if not your originals and if you want to see the difference with Silverstars, go ahead. I think after installing the boost kit, you are going with the lifetime warranty Eurolights and just swap them back when they burn out.
