Handlebar muffs

[NotAnotherHill]

I use Oxford muffs and will be putting them back on for Saturday's ride. Generally no complaints. The only issue I find is that they sometimes catch the light switch and turn off the lights. I've tried adjusting them but without much success. I tend not to ride at night so it's not a major issue but I wouldn't fancy being plunged into darkness down an unlit country road! They don't catch on the fairing.
