Low Beam Lamp Socket Polarity Question
 
2008 E350: I am upgrading to Hikari LED bulb and they need to insert their plug with the correct polarity. So the OEM plug for this H7 type socket has one with two wires and one with only one. Which is positive and which is negative?

Appreciate your assistance!

I had the same issue, I couldnít tell from the wire and I didnít have a voltage meter. So I flipped it, in till the bulb turned on. [emoji2955]

Yep, that's how LED's are done. Incandescent bulbs don't have polarity, but LED's do. If it doesn't flip on one way, then try the other.
