Permanent brake light

The left hand side as you look from the rear is staying all of the time and I have no idea why.

Initially I thought the bulb had gone on that side for braking only, but it soon became apparent that that was not the case.

I haven't done any electrical work on it since I got it a month ago.

Any ideas?

Chances are there rear brake light switch is adjusted so it is on all the time and the brake light filament on the right side bulb is burned out.

If the right side comes on when you apply the brakes and the left is on all the time, some electrical work was done wrongly. W/B is brake light hot, B/W is ground and Gray is tail light hot.

Pat- 2007 DL650A was ridden to all 48 contiguous states. I didn't quite make it to 17,000 miles on the 2012 DL650A.
Nicknames I use to lessen typing, Vee = 2002-2012 DL1000s. Vee2=2014-2016 DL1000s. Wee = 2004-2011 DL650s. Glee = 2012-2016 DL650s

I changed both bulbs today and the right side is working fine on and off. The rear brake lever needs persuasion to return to the off position, but surely a switch problem would effect both sides?

Those three colours match the feed into the problem light at the light end.

A switch problem would affect both sides if they were wired correctly. Make sure both bulbs are properly grounded for one thing.

Are they earthed at the point where the bulb touches the connector or via one of those three feeds? The problem side has had a squirt of WD40 and I have to say the spring fitment was a little sticky on that side. I guess I'd have to pop out the whole light to clean it up properly?
