I just hooked up my 3rd brake light and so far, I'm a little underwhelmed. The LED strip (which is advertised as being great for turn signals, parking lights, and brakes including 3rd brake lights), comes with a 3-wire adapter so that you can run it so that it's also on when the driving lights are on (pos 1 on light switch, +2 of course), and that's how I hooked it up. So, dim when not depressing the brakes is expected. However, even then it's way dimmer than the incandescent tail-lights are. BTW, this LED strip 3rd light is piggy-backing off of the outter most rear parking bulbs (which are small incandescent atm) - could that be the problem? (IMG:style_emoticons/default/confused24.gif)
When on-the-brakes it's a tab brighter but definitely not what it should be. Any ideas as to what the cause may be? thx |

Hook it up direct drive on a 12v battery.
Still dim? You're screwed! Nice and bright? Diagnose/repair excessive loss in brake light circuit. LEDs normally take significantly less power than incandescents and I'm betting on crappy LEDs being your issue. |
