Here's an unusual light. 380mm long x 24mm. 'E'9 marked, compact strip lights with both stop and tail function. You can use them in pairs on each side of the car or as a single, third light in the centre.
Pre-wired with three, 400mm fly leads. Supplied with a removable white silicone gasket / rear cover for weatherproofing. And here's the clever bit.
Its slightly concave by just a few millimetres so that, as you screw them in place it'll seal in the middle first then at the ends as you tighten the screws. Nice. Fits in a cut out 347 x 18mm with 360mm hole centres.
