Snowmobile Install FAQ

This will cover H13 and H4 general snowmobile installs.

H13:

Remove your factory halogen bulbs from the headlight assembly, note the orientation of 3 differently sized mounting tabs on the halogen bulb in the headlight socket. You will need to match the 3 unique tabs of the LED base to install and lock the LED base.

Take your LED bulb and remove its silver mounting base. You can remove the silver base and take it right off the bulb. There is a keyway window on the silver mounting base and 2 ears that mount it on the bulb. Move the ears to the base window and it will remove from the bulb.


Then you can install the base by itself into the headlight. Look through the headlight lens and see that it is in the fully locked position.

Hold the base with one hand in the locked position and reinstall the bulb with the other.

The bulb is 360 adjustable within the silver base for beam pattern adjustment on different applications. 
The final bulb position with the LED diodes facing left and right horizontally. Some people when they adjust the bulb into position the base turns from the locked position as well if they are not physically holding the base in the fully locked position.

Use 2 way tape, 3m or velcro tape to mount your black LED drivers so they aren't banging around.

I also recommend setting your headlight height adjuster screw to the highest setting. Then when you are on a dark trail and it is safe to do so pull over. Stand on the running boards and adjust the headlight height screw down to what you think is the optimal height for your sled. Everybody weights different with their gear on and runs different suspension settings so they preload their machine's differently. 

H4 General install:

Remove your halogen bulbs from the machine. Note how the metal bulb lock arm works.

Remove the gold base from your LED H4 bulb. You can remove the gold base and take it right off the bulb. There is a keyway window on the base and 2 ears that mount it on the bulb. Move the ears to the window and it will remove from the bulb.

Then you can install the base by itself into the headlight and lock it in with the metal arm. If you own a Arctic Cat install the Arctic Cat adapter from your factory halogen bulb onto the back of the LED base before locking the metal arm.

Hold the base with one hand in the locked position and reinstall the bulb with the other.

The final position is the power cord straight to the ground with the LED diodes facing left and right horizontally. Some people when they adjust the bulb to the power cord down position the base turns as well if your not holding it at the fully locked position.

Mount your black LED driver boxes with double sided tape, 3m or velcro tape for final securement. LED driver boxes are hot to the touch when on so DO NOT TOUCH.

If you own a H4 Skidoo with dust caps you will modify the factory OEM cap by cutting a '+' relief incision into the center of the OEM cap. If you purchased our extended caps see attached photo. You will then start tucking all the wire inside the headlight cavity and work around clockwise. Then you can pull back on the black housing plastic and put the LED driver box partially into the cavity.

We like to install a 4" hose clamp to secure the OEM and our extended dust cover so it cant back off while riding.
