Installation DIY Guide For Special LED Daytime Running Light Decoder Set

You can find this product under LED Daytime Running Lights

Case 4 (For LED_SKU45+R4)

Make sure the car is off, remove both left and right stock 9005 daytime running light bulbs and harness. Then connect back with the special decoder, the extension wire and the 9005 LED bulb.

Connect the R4 decoders to your stock harness. The R4 decoders are non-polar so you may connect them in any direction.

You may notice the LED light fluctuating for a few seconds upon power. This power fluctuation is a completely normal process.

Install the LED bulbs back and enjoy the new error free LED daytime running lights without flicker nor weak-lite-up issue.
