Hi guys, I need some direction here from the experts on an LED strip I am trying to install on my Harley. I want to use it as a brake/tail lamp. I bought it off ebay as being just that and if I hook it up to just a battery it works fine, I have a lower tail mode and then a higher brake mode. It came with three wires to it, tail , brake and ground. The problem is when I wire it into my motorcycles tail/brake light circut. When I installed it the lower tail light did not work but the higher output brake side did. I then tested my wiring on another LED tail/brake light that I had for a trailer. Worked perfect. So I knew my wiring was good. I then put the strip I wanted to use back on the bike. Now heres the kicker, I then just randomly disconnected my incandesant tail lamp bulb and on went the LED strip. It worked perfect in both tail and brake mode. I plugged back in my tail lamp and out it went. What would the connection be with my incandescent tail light? Whats happening here and is there anyway to fix it? Thanks for the input in advance.
