Annoying when cars have no Kofferraumbelauchtung! But I did not rumschnitzen the electrics and not on the car Ford KA 'well, especially since the on / off would have to be solved through a switch ... So I fitted the Osram LED light in a slightly larger Pappumrandung. The board I have chosen relatively large to the lamp a large area for safe and wobble-free fastening (otherwise switches so while driving the motion sensor a) to give. This border, I then back fitted with self-adhesive Velcro strips and velcro strapped to the substance of the trunk lining. With cable ties holding the cardboard to reliably replace the batteries I cut them just on. Disturbs the light at this point: easy hinkletten elsewhere. Perfect! And significantly brighter than a "normal" boot light. Turns on opening reliably and then again from. The light can be / adjusted towards the top down. The batteries (included) keep you safe long. For little money and little effort I have achieved so much. Class product!
