Why Upgrade to LED?

The stock halogen bulbs on youth sleds like the Arctic Cat ZR120 are dim, yellow, and offer poor visibility. Upgrading to LED gives your young rider a cleaner, brighter white beam with dramatically improved clarity and safety.

Parts Needed

• LEDPowersport™ High Power Series H4 LED bulb
• AC-to-DC rectifier (included in the kit)
• Rubber/nitrile/latex gloves — required for LED handling
• Zip ties for clean wire routing

Step-by-Step Installation

1. Turn off the sled, let the headlight cool fully.
2. Put on gloves — oils from bare skin can damage LED chips and void warranty.
3. Remove the headlight housing and take out the stock halogen bulb.
4. Plug the rectifier into the sled’s AC headlight connector.
5. (Optional but recommended) Verify DC output using a multimeter.
6. Remove the stock moisture seal if it interferes with LED clearance or traps heat.
7. Install the LED bulb — remove the collar first, insert, then clock/rotate for optimal beam pattern.
8. Secure wiring and rectifier with zip ties to avoid rattling.
9. Reinstall the headlight housing and test the LED beam alignment.

FAQ

Does this kit fit every youth 120 sled?

Yes. It works with Arctic Cat ZR120, Ski-Doo MXZ 120, Renegade 120, Yamaha SRX 120, and most Polaris 120 sleds.

Do I need the rectifier?

Yes. Nearly all youth 120 sleds use AC power. LEDs require DC power. Running LEDs without a rectifier will damage them.

Can I touch the LED bulb with bare hands?

No. Oils from your skin damage the chipset and void the warranty. Always wear gloves.

How long does the install take?

About 10 minutes if not filming. It is a very easy mod.
