3rd brake light problem 60 beetle

Post by zabo » Sat Dec 01, 2012 4:54 pm

When I added the 3rd brake light I spliced it into the left taillight wire.
The 3rd light works but now my other brake lights are really dim. Seems like itts pulling to much power from them- is there a way around this?
Im running 6 volts, my tailights are LEDs the 3rd brake light is 6v and pulling 18watts.
The electrical system is definitely my weak point. :blackeye:

Is this a daisy chain? The lamp with the least resistance hogs the current. You need to make sure each bulb has the same resistance. LEDs, are they high impedance while the 3rd lamp is good ol six volt hot incandescent tungsten bulb?
