andyherd 0 Posted June 15, 2008 Hey guys, Just fitted a HID kit to my C. Got it off ebay, never used before. It's for the H4 driving bulbs. Here's the before and after shots. Before After I'm having trouble with the main beam now though. When I pull the left stalk to turn on my main beam the HID's go out. I've tried different wiring setups but nothing seems to work. It looks like a previous owner has installed the uprated wiring loom but I don't know if this is interfering with my new setup. Any help would be much apprieciated as this is really beginning to annoy me now Cheers Andy Quote Share this post Link to post Share on other sites
boost monkey 0 Posted June 15, 2008 I would imagine HIDs draw a lot more power than normal bulbs don't they? I think you will indeed need to check your wiring, perhaps they can't deliver enough current or something. I think a start would be to take out the uprated standard headlight loom, then at least you can rule that out as an issue. :salute: Quote Share this post Link to post Share on other sites
Supercharged 2 Posted June 15, 2008 Yep, usually you unplug the dim-dip resister when installing the uprated loom so maybe the new setup needs this? Quote Share this post Link to post Share on other sites
zak 0 Posted June 15, 2008 this is normal, when you switch the main beam on the dipped beam switches off. you could modify the wiring to the relays for your uprated loom and use a diode to overcome the issue. Quote Share this post Link to post Share on other sites
