They are LED Lights
and wire up just like any other light
...... If it was a cold cathode type light
(which it isn't) it would need the separate box. If you feel uneasy then just for a test put an inline fuse on each lead and then test it off a battery
to be sure it lights then after the test take the fuses off and wire it like a regular light
to your trailer. I've installed many of these into semi trailers with no problems.
Wow....just noticed your from Philadelphia, we're just outside of reading,pa......not that many glass trailers in this area.
