Frequently Asked Questions

What does this warning canceller actually do?
When you install LED 3157 bulbs, the vehicle's electrical system can read the lower current draw as a failed bulb, causing dashboard warnings, flickering, or hyper-flash. This module restores a normal load signal so the LEDs run correctly.

How is it installed?
It plugs inline between the LED bulb and the factory bulb socket. No wire cutting or splicing is required, so it is a straightforward do-it-yourself install.

How many do I need?
You need one canceller per LED bulb that is throwing an error. This listing includes one module.

Will it work on any vehicle?
Yes, it is universal for any application that uses a 3157-base bulb. It corrects flicker and CAN-Bus errors regardless of make or model.
