Can someone kindly tell me how I can open up the backlight on my Brompton to change the batteries ?
I can not find any tutorials anywhere I see screws, but I'm not sure if a battery change requires me to open up the screws on the backlight, plus I might not be able to put the damn thing back together when screws get involved.
This isn't something that needs an enquiry to Brompton, it is self-evident. I just replaced the batteries less than an hour ago. Unscrew the Phillips-head screws either side of the central 'bump', replace AAA x 2 batteries and tighten screws. Make sure you keep track of the battery orientation, there are no markings.
Yep, you take the 2 screws out and the lens comes off - in fact IIRC the lamp comes off pretty well complete with the batteries in it leaving only the cover/backplate attached to the bike. It doesn't fall into a million pieces, though the batteries might unseat and fall out.
