Aftermarket HID Using relay harness.
Has anyone upgraded halogen projectors to HID and used a relay harness instead of directly powering the ballasts and burners from the headlamp power feeds?
I'm asking as I've been using a HID kit for a while that should work OK without a harness. Recently though I've had many more occurrences of the engine stopping when switching the lights on with the engine running. So much that I've temporarily reverted to the Halogen bulbs. I've got a relay harness but I'm not sure how I go about making the offside headlamp not cause a bulb failure warning with nothing connected to the bulb plug. I'm also not 100% sure that I won't get a bulb out warning using the relay powered from the nearside light.

Hi.
I used this kit on my mk2 zt with halogen projectors. https://www.hids-direct.co.uk/h7-35w...onversion-kit/ No issues at all. No canbus bulb errors. I didn't use a relay harness because of the reason you said. It only takes its power from one lamp so bulb out warning would happen. Do your headlights flicker or go off intermittently? Have read about this fault before on hid planet forum and it was a bulb shorting in the lamp unit causing the engine to cut out. Worth a look.. I can say the kit I got from the above link works bang on. Nice bunch to deal with as well.

The lighting is managed completely by the electronics in the LSM. Maybe that's actually why the HIDs are affecting the engine? Maybe the LSM is compromised by the HIDs and it complains to the ECU? I'm just guessing, but knowing how delicate these cars are electrically, maybe it needs a discussion. RickSta will know. TC |

Funny thing is that there's no sign of a problem unless the engine is running already. With the engine off there's no obvious battery drain or dimming lights when the h/lamps are switched from sidelights. When I get some time I'll do some experiments (might be next year then!), until then I'll have to stick with the halogens throughout the winter .

You don't need a relay - you need a decent quality ballast.

I had this happen to me twice, once it was a faulty ballast and the second time it was a faulty burner. Just replace the lot for a decent HID kit and you'll be ok.

Any recommendations? Other than price, what makes you think the HID kit in use isn't decent quality?

Again, any reccommendations for a better quality kit?
