Water in turn signals

[Loki76]

I've got the bike parked outside its under a cover most of the time.
I'm finding water in all the turn signals, it has happened before but only on the left downhill side. Now it is happening to all. Should I drill a drain hole in the bottom?

Replace your signals. Sounds like the rubber seals have perished

Check the rubber seals.
Drain hole is a good idea. Cheap, easy fix.

If you are gonna drill the lenses be extra extra careful with brittle old ones. It kinda sounds like it is condensation building up in them

Aftermarket signals are cheap and easy to install, they also add some style.

Drain hole is a good idea, but people like me sometimes have problems doing things like that to their perfectly fine signals.

The choice is yours, drain hole, replace seals (seems like it would be hard to find), or replacement signals.

No reason you couldn't try using some gasket maker to seal them up either. I would do drain holes personally, though.

Drill drain hole in the underside of the black plastic. I wouldn't drill the lens.

Just use the smallest drill bit you can find and put a hole in the bottom. I had a tail light on my car get full of water and just a few tiny holes fixed that issue.

Why drill a hole in it, think about it.....cold day, damp air gets drawn in, whats going to happen......yeah it will fill up with condensation and fog up. Then the bulb corrodes into the holder 

Drilling a hole in the case is not fixing the problem!! Look for the cause and rectify it at source.

I would be checking out the seals before anything else, make sure they are actualy there for a start, that that they are not perished and are sitting correctly. Also the holding nuts at both ends of the stem are all tight.

Gasket part no is 35613-27A00. They are about 2.5 quid each in the UK so I expect they would be 4 dollars tops in the USA.

Your not leaning enough in turns. Lean, and it'll drain.
