Lighted Hump rucksack cover (high pitch tone)

I ordered one a few weeks ago but because of the mail strike it only arrived today. I’ve noticed when it’s switched on there’s a high pitched tone (reasonably quiet) coming from the control unit.

Does anyone else happen to have one of these covers that can confirm if theirs makes the same noise ?

i think baby polar bear has 1

ive got one and yes mine makes the same squeaking noise, dont worry!:slight_smile:

Yes mine makes that noise and also if you have it on flash and it gets cold the flasher stops but it will start flashing again when it warms up.

my misses make a funny squeking noise,but then that is a differant story :smiley:

Thanks for the replies, I suspected it would probably be normal.
