Default Headlight issue
Hey all, thanks in advance for the help. I replaced my headlight with aftermarket LED. The light comes on but it stays in high beam only. When I click the low beam button the headlight stays high. The button doesn't do a thing. I ordered the same light a second time and it does the same thing, so the LED light isn't the issue. Any suggestions?

Test the power at the H4 connector and see if it moves to different contacts when you hit the switch.
If not, it's the switch.

I had thought that the RK like the SG for 16 used the dual bulb configuration. You use an bridging harness to joint them into one H4 connector that plugs into the headlight. Are you using a harness to do that?

Temporarily reconnect the OE halogen. If it functions normally, that would eliminate a faulty HI/LO switch. From there we can help further diagnose.
