Frequently Asked Questions
Why do I need an H4 warning canceller?
H4 LED bulbs draw less current than the incandescent bulbs they replace, which some vehicles interpret as a failed bulb. This module restores a normal load signal so the LEDs run without flicker or dashboard warnings.
How is it installed?
It connects inline with the H4 bulb harness, so it plugs in without cutting or splicing wiring.
How many are included?
This listing includes one canceller. Most H4 headlight setups use two bulbs, so order a pair if both are affected.
Does it work on any vehicle?
Yes, it is universal for any application using H4-base LED headlight bulbs.
