Brake light won't come on using front brake

[Silverdart]

I guess the title pretty much says it all.

Brake light works fine using the rear brake, but not the front.

Worked last weekend (AFAIK), doesn't work today. Nothing's changed other than the date on the calendar.

Anyone else seen this? Is this a common issue and easily repairable? (I did a search for the same problem but came up blank.)

Most likely the front brake light switch at the lever, quite a common failure but cheap enough to replace.

I get this regularly with my little bikes. Usually damp getting in the switch. I just remove it, easy to unscrew, and spray it with WD40 or whatever, and invariably back to normal. Had to replace one that seized. Had it happen recently after a massive rain storm.

I replaced mine (had stopped working) a few years ago.
It might be more common than is mentioned on here, maybe because it's really simple and cheap to replace.
