Hello

I have the bixenon kit from HID4U installed in my truck. I have had it in for about 4 months and it worked great, until the other day when the driver side bulb comes on for a couple of seconds and then goes out. From what I understand I need to install a relay, because I don't think my kit came with one. Unless it is built into one of the ballasts.

How do I wire in a relay for them to work right?

Thanks
Jeff

 

They should have come with a wiring harness with a relay on it that attaches to the battery and uses the headlight switch in the truck to trigger the relay to power them from the battery.

However what gets me about what you are saying is that everything worked fine for the last couple months. The other bulb I assume is still working just fine?

Can you switch the bulbs to the opposite housings. This can help you determine if the bulb is the trouble if you find the trouble moved to the other light. If you still have trouble on the one side with a different bulb in there swap the ballasts to see if that is the trouble. If you are still have it after doing these things and you are not running a wiring harness with a relay off the battery you could be getting marginal voltage across that one side. installing the wiring harness should cure this.

My understanding is that the PNP kits like HID4U use digitally controlled ballasts with a computer chip on them. One of your ballasts could be going bad. Also the reason for the harness with relay is because while these only draw 35 watts while on they take an initial charge of something like 20k volts. The stock wiring is too thin to continuously take that much absue and over time the wiring can actually melt.

 

thanks for the reply

I will try what you said about switching the bulbs and ballasts. I double checked and there is no relay there is just a wire that goes to the battery.

Do your lights come on with the headlight switch? Or do you have a separate toggle switch to power them.

You only need the relay to power if coming off the headlights.

You will have a + and a - that connects to the battery leading down to a plug that connects to a stock headlight plug and then followeed by a couple of 9006 plugs to connect to the ballasts. These may also have grounds associated with them. If it does that could be the trbl too with a bad ground. Some of the harnesses have a box that looks like a mini stereo amp with fins. That is actually the relay.

 

My lights come on with the headlight switch. I used the ground that is located next to the battery. I still haven't tried switch things around as far as the bulbs and ballasts go. I will try scuffing up the ground to make a better connection. if that don't work do you know how to wire the relay pics would help alot!!

Thanks agian

Heres the scoop

I switched bulbs from one side to the other and I have the same problem. Switced ballasts from one side to the other and problem also switched sides. I even tried to wire a relay in and all that did was instead of the bulb just going out it would flicker really fast. So I think the ballasts is bad.
