I had good brake & tail lights . One night I noticed my tail lights were very dim and I had no brake lights. Where do I start looking for the problem ?
 
Check ground from bulb body to frame to battery . Start at the battery and work towards the socket . If ok check switch ,voltage in and out . If ok check brake pressure switch .
 
Do you have factory directionals. I have found bad connections at the bullets coming from the switch. That being said, you can test with a test light. There is also a brake light fuse so far up in the dash it is unbelievable. If I'm ever in there again I will replace it with a circuit breaker.
 
Also be aware that the stoplight switches in these cars can be problematic, especially with DOT-5 brake fluid.
 
Harley Davidson makes a stop light switch that fits the hollow bolt in the rear of the MC. They are also made to bee compatible with DOT 5l
 
Stop light switch; make sure there is power (one of the two wires) if yes jump the two
wires stop lights now work switch is junk, if not check the wire all the way back to lights
troublesome bullet connectors of course ground.
Everybody should have about a 20 foot long jumper wire and a test light in their tool box.
so if you jump the two switch wires then take bulbs out and probe the socket with test
light that has a known good ground lf test light lights its the housing ground.
 
You probably should use a meter for testing. I had a problem with no brake lights. It was low voltage (3volts)to the brake light switch, there was enough juice to light the test light but not enough to operate the brake lights. Drove me nuts for a day or so. The Harbor Freight meters work well for the cost. Free with coupon
