Swapping to HID headlights but getting that annoying flicker or warning light on your dash?
You need these we-sell-hids Canbus decoders.

This set comes with two capacitors (basically resistors) that trick your car's electrical system into thinking the original halogen bulbs are still there.

They're designed to work with 55W or 50W HID xenon kits.

Just wire them in line with your new HID bulbs, and that nasty warning light should disappear.

Simple fix for a common problem.
