I just got off the EBay car parts section and saw all the "low prices?" and was wondering if any of you bought the HID kits and/or the H4 kits? I'm a little leary (too good to be true.....it is) but I want to upgrade my lighting situation asap.

I went with the H4 upgrade from 928 Specialists. Its little more expensive than some of the eBay stuff, but I wasn't ready to trust the quality or actual light output from that stuff.

I'm very happy with my 7 inch H4s. The old lights were little better than duct taping a flashlight to the bumper. The H4s give me great visibility, and were easy to install, with no wiring mods nessessary.

Stay away from the HID lights. Those low priced $50 units aren't real.

A true HID light has a power transformer. This power unit puts out thousands of volts. The lights will only operate at 5000 volts or more.

A real HID is great for brilliance on the road, but they start at $400 or more and come with special bulbs and/or complete headlight lense assemblies.

I switched to H4's and they work great. I'm going to replace them with European H4's, because the lenses are larger width-wise, so they fill the headlight area better and are slightly taller at the front of the lense. That fills the space better when the headlights are down into the fenders...

FYI,

I have a coupel of 7" Bosch H4 kits for sale. They are left over from when I bought them as a spare. The kit contains only, original Bosch (made in germany) conponets.

The kit contains:

2 - 7" H4 lenses
2 - Halogen light bulbs
2 - Rubber weather seals
1 - Instuction panflit

This conversion kit does NOT require any alterations to the existing wireing harnes. Installation takes no longer than changing a burnt out sealed beam unit.

Bosch claims 100% increase in nightime visiblity. I've replaced my seald beam lights with the 7" Bosch H4 kit on my '85 928, and the claims are genuine.

Cost: $100 usd + s/h

I have pictures of the kit and can forward it to anyone that is interested.

Any questiond can be posted here or sent to my e-mail:

I'm embarrassed to say it, but I tried them out in my 8" H4's:



Unfortunately, the beam pattern sucked and the 'high beam' was non-existent. I took 'em out.

There are newer kits, which have a better high beam mechanism, but I don't think you can get round the beam pattern problem. The optics for halogen bulbs won't focus an arc bulb properly.

The only real way would be to adapt some headlight housings designed for HID.

I'll tell you though, the initial startup was cool, and the color of the beam was nice, like driving by moonlight.

I also heard somewhere on Rennlist, that the power used by those lights are more than the stock wiring can handle. I remember a couple stories of fried wires. I heard they can work fine if you replace the wires. But I do not think you will get the beam focusing, without the proper lenses. It will just be a brighter and different colored light. You'd be better off with some colored bulbs. You won't get the real effect of the HID lights, without the lenses.

I upgraded to 8" H-4 (U.S.). Love the way they look, up or down

bcdavis - the initial startup (starting the arc) takes something like 90W, but in normal operation they only use 30W.

My kit came with its own harness, with relays and a seperate line to the battery connection. I suppose that most the other kits are the same.

What you guys need is a Headlight kit similar to what "IceShark" aka Dan Wray made for us 944 guys. You should do a search for it on the 944 boards!
