I bought the following headlights on Ebay,
DIAMOND EURO HEADLIGHT CHEVY ASTRO 85-03/CORVETTE 84-96

They appear to have H-4 bulbs that plug into the factory wiring harness plus and extra blue LED bulb with a black and red wire coming out of a socket that I don't know what to do with.

The H-4's appear to be rated at 80/100 watts

I have read several posts that warn against using these bulbs because they will fry your vette wiring.

Would someone please fill me in on the DETAILS of whether these can be used or not and if a relay kit of some sort is needed, where I can get it. What is the purpose of the blue bulb and how/where does it get wired?

Thank you, a vette newbie,
Bill

 

That kit is FINE. I have the same kit. Basically no matter what they say they are selling on ebay for this kit they are all the exact same minus some minute differances. Some have the outer ring some dont, some have a blue tint some dont. All of these kits are bassically bulbs, and a housing for the bulb which looks like whats on your car now. The kit I have is the one with the outer ring. You will not damage anything if you hook up that ring...all you have to do is run wires from your running lights to these (and I think they use bullet connectors) just make sure you use the same guage wire cause if you go smaller you will burn some stuff up.

 

Thank you for the response!

 

I ordered mine last week and they should be here today hopefully. I hope they will be a little brighter with the H4s. I am going to put sylvania silverstars in them which are a brighter light so hopefully that will work. I am going to take pics of the lights with one in each side for a comparison. Glad to hear about the wiring also. Thanks for the info.

 

Those kits are generally cheap junk. You'll know it's junk if you paid less than $50 each for them.
Now that I've got that out of my system.....

I have Hella's with 80/100W H4's and the C4 wiring is holding up okay. I haven't even had to uprate the fuse.

I've run 80/100 H4's in my 1973 Chevy van since it was new and the only problem I had was the plastic around the connectors overheated and got soft (this after more than 18 years, tho). I took care of that problem by bolting each of the three bulb prongs to the wires using new ring terminals and tiny brass machine screws and nuts. (the overheating came from poor connections; standard spade terminals, over the years, develop a lot of resistance.)

The blue bulbs (they are called "city lights" by old skool Euro-guys) are pretty darn useless on a C4, since you won't even have the headlights showing unless they are on. If you must have them operational, though, you'll have to figure out how to wire them yourself.
Good luck! (remember; you promised pictures!!)

K Larry, they are not cheap junk. Just because they were not more than 50 bucks dont mean squat. Its true that sometimes you get what you pay for but in this case what I got was really good quality. I like the look, the easy install, and they are ALOT better than stock. Now the kit you have might be better or brighter than mine or whatnot but I like what I got. Did you have this ebay kit larry cause your talking down as if you tried it and proven to yourself its not as good as what you have now or are you just talking OYA. As far as that outer ring, yes it will be on with your parking lights and YES they will show but first you have to turn your headlights all the way on then go back down to the parking lights, your headlights will stay up then otherwise they will be in the down possition.

 

I may have started my previous post off a little harshly, and I apologize to you and everyone else for that. Hope this post clarifies my position a little better. I also hope the bulk of that previous post had useful information for you.
That said...
I've purchased more than one set of cheap headlights. I've also purchased more than one set of quality headlights. My experience is that...especially in headlights...you do get what you pay for.
I upgrade headlights in order to get more/better light.
I have a whole shelf in my garage of EagleEye, Pilot, Diamond Cut, etc. lights. Those lights are on the shelf and NOT in my cars/trucks, because they don't put out the light that the Hella and Cibie lights do.
If you paid, say $45 for your lights, about $15 of that is for the little blue bulbs and their support system. That's $15 worth of LIGHT that you are not getting.
It's all in where your priorities lay. Do you want cheap lights, cool-looking lights, or do you want lights that work the best they possibly can? Those are the choices...you pick yours and I'll pick mine.
Hella/Bosch/Cibie or Pilot/Diamond Cut or Eagle Eye?
I'll also say this; I don't have much regard for a decision that sacrifices performance in order to get something that looks cool. That's what the import guys do all too often, and it's called a certain cereal grain that grows in paddies.
Good luck with your project.

Cool, that clears it up alot. I see your point. I still like mine as it was an upgrade from where I was and most likely in time I will upgrade to the hella after what you have said and of course I will research first before I jump into it. Thanks!

 

Well we will see shortly how they turn out. They are supposed to be here today. Now the way I go about doing stuff, much less that I have a bad/severely sprained ankle, well it may be more than a few days. lol But, I do have to say that sometimes because you pay more doesn't necessarily mean you get better. Case in point are cold air intakes. One of the best you can get for the C5s is free (zip tie mod). So there goes that theory. But I will admit that everything isn't always a great deal because it is cheap. Hey, I am experimenting anyway. If it doesn't work out then we saved the rest of the forum guys some money and headaches. Glass is glass in my mind, it is the bulb that is going to make the difference. And as stated before I plan on putting in Sylvania Silverstars because I know for a fact they are pretty good.

 

I bought the same Crystal Diamond cut reflector style replacement headlight capsulls made by Adjure. it has the blue LED in it but i have something else planned for lighting..... H4 Bi Zenon HID 10,000k conversion kit. Now I dont care what headlight capsulls you use weather it be Hella or what i bought that thing is going to throw some nice light. I will post pics once i get all the parts in

 

I am planning on doing something very similar to that. I was reading on a site where they had the conversion for the H4s. I'm looking forward to finding out how it works out for you. Can't wait to see the pics!!And you are so right. Just about anything is better than stock.

 

I've seen a similar set of headlights at Autozone, think they were $45. I have no problem with the stock ones, except the gears. I am looking for a brighter headlight bulb though if anyone knows a good replacement.
