Ask a Question
  • I have a hb3 type light on my corolla that is negatively switched. How do I change the loom setup to suit my negatively switched lights?

    Hi, Our loom works on both negatively and positively switched vehicles, no modifications are required.

  • Hi, I have a 2015 Hyundai ix35 EL2 wagon bulb type is HIR2LL or D3S (from owners manual) can you advise if this harness is suitable as a plug and play? I intend fitting a small light bar to the vehicle. Thanks Pete.

    Hi there,

    Does your 2015 Hyundai ix35 use D3S (HID Bulbs)? If that's the case our wiring harness is not suitable for your vehicle. If your car uses HIR2LL bulbs, our wiring harness is not plug & play but you can make it work  by swaping the HB3 connectors of the piggy back adapters with HIR type connectors. I hope this helps.

    Thank you.

  • Can you just but the ADAPTORS for your headlights

    Hi travis,

    Unfortunately we do not sell the adaptors seperately.

    Thank you.

  • Will this harness plug n play in Toyota yaris and Toyota rav4

    Hi Mick,

    Our wiring harness comes with H4 and HB3 piggyback adapters, and your Toyota yaris uses H4 bulbs and Rav4 uses 9005(HB3) bulb for high beam, this harness is compatible.Thank you.

  • My ute lights on my Toyota hilux stay on all the time when the motor is running because we use it in the mines can I use this wiring kit on my ute regards William.

    Hi William,

    This wiring harness kit allows your driving lights to turn on when your car's high beam turns on, it automatically switch off the driving lights when you flick your high beam off to make it street legal. If your Toyota hilux's headlights stay on all the time then your driving lights won't turn on unless you turn on your high beam.


  • Hi; Could you please tell me if this harness is suitable for an Hyundai i30 2010 cw. Thankyou

    Hi there,

    Your 2010 Hyundai i30's highbeam uses H1 bulbs, so this wiring harness is not a plug & play solution because we only include H4 and HB3 adaptors.

    Thank you.

  • Hello Can you tell me if this product will suit my 2017 Holden Trailblazer LTZ?

    Hi there,

    What light bulb your Holden Trailblazer LTZ uses on the high beam? The 2017 Colorado LTZ that the Trailblazer is based on uses H1 globe, so this wiring harness is not plug & play for you. If you are a savvy DIYer, you can modify the piggyback adaptors by replace HB3 connectors with H1 connectors. If you have more questions please feel free to email or call us. 

    Thank you.

  • Is this suitable for ML Mitsubishi Triton???

  • Hi I have a Landcruiser 79 series duel cab 2015 will the harness suit looking at purchasing Spectra 7in

    The 2015 Landcruiser 79 Series takes H4 for high and low beam, so the wiring kit is compatible with your car.

    Most 79 series landcruisers take H4 for high and low beam so our wiring harness is compatible with it

  • Hi, is this harness suitable for a Hyundai i20? Looking at installing a lightbar. If not would you have a harness suitable I could buy?

    The Hyundai i20 switches from low to high beam through the motorised flaps inside the fisheye lens, so you will need to modify our wiring harness then splice into the factory wiring that controls the motorised flaps. If you are not comfortable with the process you should seek help from professional auto electricians.
