The premium headlight accessory upgrade is a sleek way to personalize your bike and make sure you're seen while riding Rad.
Watch the video and follow the steps below to install the premium headlight on your bike. This guide uses a RadCity 4 but the steps will be the same for most models.
Tools needed:
- 3 mm Allen wrench
- 5 mm Allen wrench
- 8 mm wrench
- 10 mm wrench
- Torque wrench with a 5 mm Allen bit
- Phillips head screwdriver (optional; to remove the rock guard)
Notice: Hardware may vary (bolt head style) and/or require different tools. Use the appropriate head size and type of tool for your bolts. Ensure the tool is pressed firmly into the bolt head and turn slowly to prevent stripping.
- Get the bike ready for installation. Turn off the bike, remove the battery, and press and hold MODE (or the power button) to discharge remaining power.
- Locate and unplug the headlight connector. Trace the cable from the headlight to the connector. Pull each side of the connector directly apart, without twisting, to unplug.
- Remove the stock headlight and headlight mounting hardware from the front fork.
- Use a 5 mm Allen wrench and a 10 mm wrench to remove the headlight mounting hardware. Set the hardware aside; it will be used to install the premium headlight.
- Store the old headlight for later use, or recycle according to local rules.
