Lighting and Bulbs

If you are going to buy LED bulbs, buy the cheapest ones from Amazon/eBay and order extra for DOA bulbs. You will find that most of the time they are the exact same bulbs that you get from the higher end shops, only they repackage and sell them for a higher profit. If you order 20 for the price of 3 and get 2 dead ones, you still come out far ahead of the high end rape shops.

I also look at the leads going up the side on the wedge style bulbs. Most are just fine, but some of them don't go up the entire side of the wedge and can cause issues.

192 and 168 bulbs are compatible with each other, just different amperage/brightness/life expectancy, with the incandescent 192 being 2 CandlePower pulling less amps and longer life and the incandescent 168 being 3 CandlePower pulling more amps and not quite half the life expectancy.
