Hi Eric. I started using HID 55 watt bulbs in my 86 Toyota pickup, and then in my 86 Sunrader RD. They are 55 watt 5000K, I got them from DDM Tuning and they are currently around 55$ plus shipping. However you must also get a set of H6054 headlight bases that you insert the HID H4 bulbs into that fit your Toyota. I just pulled out my 3rd set of the entire system from my pickup, and my first set from the sunrader. They failed without warning. They were incredibly bright without oncoming traffic flashing me, but when they went, it was everything at once. So I popped in a set of DDM Tuning 35 Watt LED H4 lamps and they are bright, but the light is scattered and the high beams go way too high in the sky. So now I am going to the Sylvania XZE H4? also known as a 9003 bulbHalogen bulb, which they claim is the closest thing to an HID Best price I found was at Ebay +/- 35$ a pair. The cool thing about having the Headlight lens assembly that I got for the H4 HIDs is that it will take ANY H4 bulb, LED, HID, Halogen, Conventional. I don't trust the HID systems not to catastrophically fail anymore, could be the brand? But I can tell you that the HID system is pretty complex, with a lot of components to wire up and find a place for. You really can't connect anything wrong because the connectors are all different, but its way more complex than just replacing your normal headlight bulbs. Good Luck!

I should also add that the 5000K color temperature which is a pretty pure White gives the best visibility. As you go down from 5000K things get "Warmer" or more yellow orange. As you go above 5000K things get "Cooler" or more Blue, even Purple. Old fashioned incandescent bulbs are more yellow. 5000K is where the best visibility is.

Here is about "Color Temperature" although some headlight go as high as 9000K (purple)

Here is the Housing kit that you put the H4 bulbs in
