[Little yellow Brompton]

I have two of these, one each on the Brompton and the Voyage. Both have water in them to varying degrees. I have the Bromton's off and removed the heatsink/top shield to dry out the lamp, but I'm left with water stains and a film over the reflector. Anyone know how to open the lamp(s) any further to allow me to clean the reflectors?

is this a problem with these lights?
I purchased one recently. And no doubt only a matter of time until it's used in a downpour.
Any tips as to how to stop water ingress?

I have a feeling that the water is a result of my using a hose pipe to wash the bikes. The water seems to be coming in from the joint between the heatsink and the body, so I will reassemble, I think, with a smidgein of silicone sealant.

I've had mine out in downpours without any signs of water entry. Yet

Try this set of photos of the disassembly of the light (especially page 2). It might help you take it apart further...

Thanks for that, I coudn't see how the reflector came out of the body , but as it's onbviously part of the lens it woudn't get me much further anyway. The pic that showed the LED still atached showed me that it just slid out , I did that then polished the reflector ,through the aperture left ,with a cotton bud. Thanks for your help!

Back on the Brompton now, and back to it's retina spotting self! Don't ask which muppet looked at it and spun the front wheel before re assembly and had to do it with purple patches wherever he wanted to focus!
