LED-to-H4 Headlight Conversion Harness - Honda Grom (2017-2026)

Grom LED-to-H4 Headlight Conversion Adapter Harness

Looking to swap out your stock Grom LED headlight for a traditional halogen setup (RuckEye, Classic 7", etc.) or an H4-compatible unit like Monster Eyes or 12V LED Pods? This adapter harness is the perfect solution! This harness adapter provides a steady 12V power source to your new headlight while fully maintaining High/Low beam functionality.

The factory Honda Grom LED headlight connector only outputs 6V to the low beam circuit, which limits compatibility with many aftermarket 12V headlights featuring high and low beam functions. Because of this, additional wiring modifications are typically required when installing a custom 12V headlight setup.

To simplify the process and eliminate the wiring headache, this adapter harness is designed to make installing an aftermarket headlight quick and straightforward.

• No wire cutting or permanent modifications required.
• Fully Reversible: Easily revert to your OEM headlight setup at any time.
• Instant Power: The headlight activates as soon as the key is turned to the "On" position.

Note: While High/Low beam functions are maintained, the high-beam indicator light on your dash will be disabled with this harness.
