I have 4 H3 halogen lights installed on my truck now. I was wondering if I can use the existing wire harness and swithch with theses LED lights?

I dont see why you cant.just hook up the positive and negative wire and you should be good to go.the led lights draw hardly any power.they are great lights and good people to deal with. Good luck

yes you can. the 4 H3 halogen lights drain 220 watts from yur vehicle and this 4 led lights just 108 watts so if you have made the instalation whit some rellays for compensate the drain its better. In a few words, just change the lights the existing wire harness and switch are enough.

i cant see why not,they should draw way less amps than your old lights.I used to work as a mechanic,although i no longer do,they should work great for you

Dear Ron, Thanks for your inquiry. The lights must work with wire harness/switch and you can check the wire harness from http://www.amazon.com/Universal-Wiring-Harness-Switch-Driving/dp/B00DKWJ1RS/ref=sr_1_1?m=AA3DW73OVKOAR&s=merchant-items&ie=UTF8&qid=1395024413&sr=1-1&keywords=B00DKWJ1RS. Hope this can help.

Yes, just plug in where the old headlights were. 9003 H4 Headlight Bulbs go in those lamps.

Hi, You would need additional adaptors to ensure that the wire harness is plug+Play with your OEM H13 headlight harness. These headlights come with an "H4" style plug, and the adaptor converts this wiring to "H13" Steve

I'm not really a wiring expert, but I think the way this harness is fused, you'd need 2 harnesses for four lights.

One they already have halo's that probably aren't as bright as you'd like but as far as I know no headlights are specifically designed for that. You need to open the seal somehow there are various methods of how to do so online. Then re seal them if you are adding strip to them. I would recommend going to your nearest truck customization shop and seeing what they reccomend.

Yes! This is why it is important to purchase the Hella wire harness specifically for these lights.

No wiring harness, you will need to order wire, connectors, switch, fuse holder, and light relay kit all inexpensive at Amazon, but it is worth it when you see these lights in operation, they light up everything for half mile, can't have them on when other vehicle's are approaching. Heavy duty aluminum construction whit glass lens.

Yes, you will need to purchase a wire harness either a H-4, H-4 dual light or a H-7 harness the price is between $15.00 to $20.00.

The wire harness will work with any light system. The only exception is the connector at the light will be different. Depending on the installer experience level and mechanical abilities all that needs to be done is to hard wire the connector(s). To do that cut the connection at the light for the (+) POS and do the same for the harness, then splice the two (+,+) and (-,-) either with a solder or butt splice then add the heat shrink. NOTE: USE A MUTLI METER TO TEST POLARITY. Another way is to just use the supplied harness that comes with the 4000i. Run each individual harness to the same toggle switch at the dash. The toggle switch only supplies a low amp 12 volt power source to energize the relay. To energize the 2nd light/relay add splice connector to the switch output terminal 86 to the relay. Now both lights will be energized by the same toggle switch. NOTE: WIRING DIAGRAM FOR HELLA 4000i IS ON PG 9 OF INSTALLATION MANUAL.

No new wiring harness for under the truck. New harness has it's own wiring that connects directly into the truck wiring at the opening from the existing taillights.

I only installed the headlight (no halo ring). But the light didn't require a different harness. It was plug and play. Very easy installation.

For my 06 cobalt it was just a swap out of the bulbs to the halo lights the only part that was a lil more time consuming was the finding the groundw wire and parking light wire to hook the LEDs to but I found it on one of the ask websites, it was about a hour job except for the searching online to hook up the halos and LEDs

I wouldn't swap the halos. The CCFL halos are the way to go. LED's aren't a fraction of the brightness of CCFL. As for the HID kit, all you need is a h3 55w kit. I found mine off eBay.

I have not installed mine yet, but, I believe you can change the bulb only to an HID lamp. Also, to get the Halo's and led's working, you need to tie them into the parking light circuit, that would be the brown, or, brown striped wire that feeds power your old parking lights. Good luck.

You can reuse the three(3) screws that hold the current headlight, they line-up correctly. The new headlight also came with wire for the extra led light, but I had to buy quick splice connectors to splice it into the park light.

As far as fitment goes it should be fine. You may have to splice into the existing wire harness for the lights. An adapter plug is included.
