headlight conversion relay kit does its job January 5, 2018

Reviewer: Dutch

The high/low headlight conversion wiring kit does what it's supposed to do, fits right out of the box.
Added bonus:
Leaves low-beam on when switching to high beam...
(Did not know this when purchasing so it made testing what plug was what (low/high) a bit interesting to say the least)...
It's fitted with four (4) 9006 plugs.
So if you want to use the "official" high-beam-bulb (9005) you have to change out 2 plugs.
None of the 4 plugs are marked to show what they are supposed to be (low/high).
9006 = Low beam (usually 55 W)
9005 = High beam (usually 65 W)
