What is the screw size (mm) for the rear view mirror mount

[seamax]

on an 89 GS? And also my turn signal indicator only comes on when i signal left and not right. Any solutions to this? Thanks.

The mirror is an M10.

Do you have LEDs for the turn indicator? because I have heard the problem you mention in that case (polarity is off).

M10 as ina a 10 mm screw would fit in the mount?

Also yes, I converted all my indicator lights to LED's. In that case, how do I turn polarity on?

"Polarity is off" as in "Polarity for one of the current flows is not right for the LED" (The LED is a diode, thus conducts current only one way). No easy workaround to that, you have to rewire the whole shebang. Have to have a look at the circuitry before I can help you on that.

M10 as in M10. 10 mm metric fastener thread for those who still measure lengths with their body parts (sorry for the slur, had to get that off my chest).

Oh, and BTW, 10 mm means 10 mm thread diameter, not 10 mm wrench size (since you seem to classify screws like that sometimes).
