Product Details

Plug-N-Play: Forget about crimp-on wire taps, these convenient "Y" pigtails make splitting or doubling the signals from your headlight system easy and clean.

Double High Beams: So you already have a halogen high beam? When retrofitting a bi-xenon projector; you can harness the stock high beam power to activate the bi-xenon solenoid at the same time, thus doubling your high beam output.

Quad Retrofits: Use a splitter to run two low beam harnesses in parallel for four ballasts and then activate two pairs of bi-xenon solenoids off a single high beam output. Three total splitters needed.

Sport Bikes Retrofits: Instead of a single low beam and a single high beam, you can retrofit two bi-xenon projectors and split the single high beam output into both projector solenoids. Instant dual low beam dual high beam setup! (generally H7 Male to 9006/9006 female)

All Fitments: For the input, make sure to select the size that matches with your stock high beam bulb type. The output will generally be the female version of that same bulb, coupled with a 9006 to plug into your bi-xenon projector solenoid.

Great fitment


Fitment was perfect and quality felt good. Only with it was marked what was high and low beam. Unfortunately I wasn't to use them, had to go with the H13 realy harness for my M-LED 2.0 install.

Description explains these beautifully!

Grayson Terry

I use these on almost every set of headlights I retrofit. Great for a vehicle that has an original halogen high beam separate from low beam. Double the high beams with halogen and HID projector.

2013 Camry Splitter, Quad High beams


I used this splitter on my both of my 2013 Camry's and on my 2015 CT200h and got quad high beams. Fantastic product. Plug and play to double your high beam output.

Highly Recommend.

Simple and easy


Just put these into my RSX and it took less than 15 minutes, and that's only because my high beam plugs are a little hard to reach. Both stock halogen and the projector high beam turned right on. Can't wait to see what my night-time visibility will be like now.
