Does Wiring Polarity Matter for Installing Optronics Clearance or Side Marker Light MC32AB

Question:

Since both wire coming off the light are black, does it matter which is negative and positive? Im also assuming the bulb is replaceable? Thanks! Trailer Clearance or Side Marker Light w/ Reflex Reflector - Rectangle - Amber Lens - White Base

Yes, the Optronics Trailer Clearance or Side Marker Light # MC32AB can be wired with either of its two black wires used for ground or for power. Since this is a single-function/single-bulb light it does not matter which is which.

For a replacement incandescent bulb for this light you can use part # A194B which is a 194-type standard bulb.
