I connected this light to my 03 road king. Light works, license plate works, but the brake light doesn't work! Any ideas?

Take the four screws out the back of the housing and look on the circuit board that the three pins are soldered to. Itll say grnd tail and brake. Then wire yours accordingly. On my 04 night train the red was on ground so I had to switch red and black

what bulb does this take?

It doesn't take a bulb. It has an LED panel inside the housing with like 12 LED's.. The complete light assembly plugs into the factory plug behind the light.

I bought one of these lights but it never came with the adapter plug

This is the easiest "Plug and Play" that I've purchased. It also looks really good on my 2016 Harley Fat Bob. My purchase did not have any problems. Just send it back and hopefully if there are any problems AMAZON will step in.
