But back to the light.....
I fitted one about a year ago, with the indicators in. Wires are crap, as has already been said.
But they take such little current they don't need to be thick.
SO, just a tip- before you fit it, make a note of where the wires go in and are soldered to the board. When they come off it's lots easier to re-solder them.....
And regarding how bright the indicators are- I've also fitted mini indicators as well, so easier to see. (Same on the front, side repeaters and mini's).
And they'll STILL say they could'nt see me.....

It's not falling off, it's an upgrade opportunity.
