Silverholder LED light strip install to daytime running lights on 2023 Hyundai Elantra CN7.

JAN 10 2023 UPDATE::
The strip has started to malfunction. It has developed a dark yellow spot near the power side about 6 inches down and the entire strip has started to flicker. I've removed it for now, and sent an email to the company that sells it to see if they will stand behind their warranty. Stay tuned.

** Disclaimer ** Do not attempt this unless you have a decent understanding of how vehicle electrical systems work. Also, you will be tapping factory wires so this may impact any warranty claims related to the headlight asssembly. You have been forewarned!

For this installation, I wanted the strip to power on with the stock DRL and remain off if the parking brake was engaged. To achieve this, I needed to tap both the DRL power wire and the headlamp power wire at the driver side harness. The DRL wire is green with a black line, all by itelf on a row of 5 terminals. The grey wire is the headlight. A diode is attached to each of these wires to prevent backfeeding 12v back to the DRL from the headlight and vice versa (note: the DRL turns off when you activate the left turn signal, so this will shut off your strip if your lights are off. To prevent this you can tap the passenger side DRL wire using a third diode, thus giving your relay coil three power sources. The relay is neccesary because for some reason, the grey headlamp wire doesn't provide enough power to light up the strip (I know, its weird) The coil of the realy is powered from the diode-protected wire tapped sources, and the switch end of the relay is connected to the car battery. I was going to use a fuse tap in the engine fuse compartment but the one I bought didn't fit.
