adding another brake light - help

As mentioned earlier, I would want a 3rd brake light not for additional brightness but to get it higher.  Same reason all other vehicles have them now.

Yes David, I was kind of thinking of adhesive velcro too.  I would like something a little more permanent but without holes, but if I can't use magnets, I don't know what else?  Too bad Forest River didn't leave some places in the window frame to insert one.

Gretchen - thanks for the pic and write-up.

Goose - not a bad idea.

Here it is!  The new brake light.  Turns out it is also an additional turn light.  I will feel MUCH safer driving now knowing others can better see when we slow down seeing as the factory brake lights are so pitifully low. 

This is a Optronics 11 light LED 3 wire Streamline light. I got it at the camper store around $20.  Bought one 1/ 1/2 x 4ft. aluminum angle at Lowes.  The light is completely enclosed in plastic, so nothing to waterproof there.  I mounted it to the angle with stainless nuts and bolts, fished the wire thru to the back where I butt spliced and heat shrink wrapped the connections, than making one small hole all the way thru, fed the wires inside and covered in a neat little  tape backed track running over to the side and down into the storage compartment where my handy husband did the wiring. 

The ends of the angle are closed with a neatly cut piece of cedar silicone calked in just so and a good bead of caulk along the top ONLY.  I left the bottom unsealed to act as a drain incase any water does get in.  It is held in by two stainless 1 inch screws, but mostly the caulk held it.  Not bad for a housewife, huh? 

Now, if anyone has made an awning for the back window, I would love to know/steal your idea.  I am thinking a piece of vinyl soffit would be light and let wind blow thru it.  I would like to see if I can do this with magnets so as not to make any new holes.   Thought appreciated.  I can't wait to get camping!!

Definitely interested.
