Greg F Posted March 5, 2018 Report Posted March 5, 2018 My brake lights work, but only if I stomp on it like no other. Most the time, just applying the brakes normally, do not light them up. Any ideas on how to fix this as a couple of people have gotten upset while following me. (New brake light switch, after market switch, ?.?) Thanks, Greg Quote
Jerry Roberts Posted March 5, 2018 Report Posted March 5, 2018 Just to be sure that the problem is the switch , jump the two wires together and see if you now have a brake light . Both the original type of switch and the aftermarket style are available at a good price . Quote
greg g Posted March 5, 2018 Report Posted March 5, 2018 Hydraulic switches get corrupted by old brake fluid, corrosion. Brake light circuits can develop electrical resistance in connections, grounds can get corrupted with age. I just changed my switch last year it made a big difference, I have also powered the switch through a new independent wire with an inline fuse, and run a dedicated wire from the light fixture to a good tight ground. Also make a grounding line from your body to the frame or engine. Quote
Greg F Posted March 6, 2018 Author Report Posted March 6, 2018 Will try a new switch and hope that helps before I get rear ended.... Quote

Greg F Posted March 7, 2018 Author Report Posted March 7, 2018 Will try that, if the new switch does not help my problem. As always thanks for the ideas...Greg Quote
