Headlight Assemblies
About Headlight Assemblies
The headlight is the main light on the front of the bike. It lights the road ahead and makes you visible to oncoming traffic. Riders replace a headlight because of a cracked lens, moisture inside the housing, dim or yellowed output, or to switch from halogen to LED.
Start with size and shape. The samples show round lights of 5-3/4 inch and 7 inch, and a headlight must match the diameter of your bike's mount. Then pick the light source, halogen or LED, and the extras, such as halo rings, built-in LED turn signals, and chrome or black finish. Check whether it is a direct replacement for your model or a different style that needs mounts or a harness adapter. The category also lists dirt bike parts, such as replacement headlight plastic for KTM, headlight guards for models like the Honda CRF300L and replacement glass.
Brands in this category include UFO, ZETA, PATHFINDER, CIRO and Drag Specialties. Bulbs are in Light Bulbs & LEDs, covers are in Lenses and mounts are in Hardware, Mounts & Brackets. Pick your machine in the Ride Finder at the top of the page, and see why a part did not fit and how to avoid it. The whole group is Lighting & Lamps.
FAQs on motorcycle headlights
What size headlight does my motorcycle use?
Check the owner's manual or measure across the front of the existing headlight. Round headlights are sold by diameter, with 5-3/4 inch and 7 inch common on many cruisers. Dirt bikes and sport bikes often use a shape made for the model, so use the Ride Finder and read the fitment line.
Can I swap a halogen headlight for an LED one?
Often yes, if you choose a complete LED headlight made for your bike's mount and connector. Putting an LED bulb in a housing built for halogen can scatter light and dazzle other drivers, so a complete assembly is generally safer. Check local lighting rules too.
Why is there moisture inside my headlight?
Condensation can come from a damaged seal, a cracked lens or a blocked vent. Dry the unit and watch it. If the moisture comes back, the seal is probably failing and the assembly or the lens should be replaced. Check for cracks first.
Does a headlight need to be aimed after installing?
Yes. A new headlight or mount can change the aim, and a beam pointed too high dazzles oncoming drivers while one pointed too low lights too little road. Aim it with the bike on level ground and loaded as you ride, and follow your manual's instructions.
Can I fit a headlight from a different model?
Only if the mount, size, connector and wiring all match. Check the listing's model range and use the Ride Finder to confirm. Some headlights come with mounting hardware, while others need extra mount parts or an adapter.
