Quick Tip: Most Projector style headlights will use an 80 or 90mm halo size 

Our Halo sizes range from 55mm to 180mm size. Below is a conversion chart featuring MM/CM/Inches

Method 1: Without opening headlights

Choose the size using visual cues. With most projector-style headlights an 80mm halo fits around the LED projector. So, if you have standard projector headlights as pictured below you will need an 80mm halo size. We have also included what some bigger sizes would look like next to a standard projector-style headlight.

Method 2: Open your headlights and measure

  1. Non-waterproof headlight halos are installed inside headlamps. Since headlamps must be opened either way you can also wait to order your size after opening.
  2. Remove/ open the headlight lens: This will give you access to the headlight assembly.
  3. Measure the diameter of the headlight: Use a tape measure or a ruler to measure the diameter of the headlight assembly from one end to the other in the area you want to mount the halo ring.
  4. Record the measurement: Write down the measurement and compare it with the sizes available and order the halo ring that is closest in size to what is needed. Sizes don't always have to be exact, and we recommend ordering one size down if your size is in between the two different sizes we offer.
  5. Halo ring sizes are listed by outside diameter, in millimeters. So, an 80mm ring is 80mm in outside diameter.

What if I choose the wrong size? If you accidentally choose the wrong size no need to worry, we can exchange it for a different and correct size.
