Hey all,
Just want to share my experience fitting these LED parkers bulb on my s2 galant.
Bought it from ebay for couple bucks, pulled out the front grill and headlights off my car, installed these 2 bulbs, then found out that the left hand side parkers didn't light up. Strange..
Test it with multimeter and found out that the left hand side parking light bulb holder has -12 Volt DC instead of +12 Volt DC.
So I swapped the wire around to get +12 Volt reading, then the LED is ON.
I think being LED light the current can only travel one way, diode principal.
But is this only happened to my car, or all other legnum/galant will have -12 DC volt on left hand side headlight as well?? :huh:
