Nick Posted September 29, 2019 Share Posted September 29, 2019 I have some external lights which have motion sensors built into the face of them. The issue I have is when it rains (all the time) water runs down the face of the light and triggers the sensors, so they just stay on all night. Even if I have sensitivity to the lowest setting. Pic of culprit (I have 4 though): I want to make/get little roofs to fit on them, so rain doesn't run down the front but down the back. Anyone got any bright ideas on how to do this but also look good? I was thinking a 3d printer might be able to but I don't have one. As I could make it so they just slot on without any fixings.

Tug Posted September 29, 2019 Share Posted September 29, 2019 Ally angle sprayed black and glued on? That would provide a small roof to deflect the water. Quote Link to comment Share on other sites More sharing options...
m4inbrain Posted September 29, 2019 Share Posted September 29, 2019 Yeah, 3D Printer of course would be able to fix this in a few hours (printing is slooow ) with a clip-on solution, if you're a bit knowledgeable in CAD and have proper tools to measure (calipers etc). Don't know what kind of tools you have, if you have a small bender, two steel rods bent to shape with the shade (made of tarp, maybe) mounted between them would work, or as Tug mentioned, alloy angles. Or if possible, you just mount this specific one higher, the drain would shield it in that case. Or, if you have, two small steel plates that you hotglue to the front, triangular shape/like eyebrows, so the water runs off left/right instead of over the lense.

Fly In My Soup Posted September 29, 2019 Share Posted September 29, 2019 Needs a hood/shade/rain deflector on top... One from an tx mounted fpv monitor would do the job They're like this but rectanglular Quote Link to comment Share on other sites More sharing options...
Mack1 Posted September 29, 2019 Share Posted September 29, 2019 I knocked this up at work out of stainless steel for ours. Not because of the rain problem but neighbour was moaning about the light waking them up in the mornings as I'm going to work. Works quite well and seems to keep everything dry as well. 1 Quote Link to comment Share on other sites More sharing options...
Ninetiesbeard Posted September 29, 2019 Share Posted September 29, 2019 Some sort of a shroud should do the trick. Could print one up or try and find an industrial duct around the same size and angle grind it to suit Quote Link to comment Share on other sites More sharing options...

What's a good cheap tool to cut thin alu sheet with? 1 Quote Link to comment Share on other sites More sharing options...
