Headlight Bulbs Harness Conversion Kits

[SHIRE.ZRE]

Hi Guys,

I am planning to change my headlights (entire housing swap) to some aftermarket ones that have projectors in them, now the problem I am facing is that these headlights use H7 bulbs for both Hi and Lo beam and my ZRE Corolla came with HB3 and HB4 bulbs from the factory.

I was wondering if I can find some sort of wiring harness adapters or conversion kit that can plug into the factory wiring loom meant to connect to the HB3 and HB4 bulbs and convert this connection to H7.

I don't wanna go splicing and cutting factory wires to suit these aftermarket headlights.

Has anyone done this before?

I don't think you need to modify the factory harness because the bulb connectors are part of the headlight. So the aftermarket headlights would have them changed for you? Just plug the factory harness into the headlight.

This is based on my zze headlights. If your factory harness actually plugs directly to the bulbs... You can make an adaptor using male/female plugs from ebay or at www.autolumination.com

Note that ebay aftermarket projector headlights usually have very poor output. Although I noticed they are improving.

The factory harness is bulb specific and it plugs directly into the bulb itself, so that is why am asking. The factory harness would have connections to suit the HB3 and HB4 bulbs and even though the aftermarket projector headlights would come with a H7 bulb (and maybe a connector, although I doubt it) it means I would have to splice into the factory loom to fit the H7 harness and I don't wanna do that.

here are some male/female headlight plugs to make up a conversion harness

Thanks mate, I reckon this will solve it. I would need to get a female H7 plug to go into the bulb and an HB3 or HB4 male plug to go in the car wiring harness and connect these 2 plugs together to make-up the adapter.
