1800 brake lights stay on

[pianowiz54]

I have a 2002 GL1800 trike. My brake lights stay on all the time. I have ridden the trike around my neighborhood to see if it goes off, but the lights are still on. My shop manual says to check the front switch first & then the rear switch, but if either of them is defective would that still keep the lights on all the time? Thanks for any help.

Yes, either switch can cause the brake light to stay on. Check the switches and the adjustment on the rear switch. It may just be out a little.

Changing the front switch is pretty easy and is inexpensive. I think 10 bucks took care of it for me.

The rear brake light switch is behind the right engine cover, where you check the oil. Right behind the dipstick is the master cylinder, on it's push rod is the switch. Listen closely as you slowly push the pedal down, you should hear 2 clicks, if not you probably need to adjust the tab that contacts the switches.

I would start by making sure that the front brake laver is returning to its neutral position. Here is what can cause a lever not to return:
- lack of lever maintenance (clean, inspect, and lube)
- after market levers
- overfilled reservoir
- front brake system needs inspected, and the fluid changed
