Any suggestions on a good looking surface mount third brake light?

Just looking for ideas. I am wanting to add an additional brake light to a modified roof rack. I have 30" or so to play with. Would prefer powder coated or black anodized surface mount. Any suggestions?

Currently leaning toward using 4 or 5 of these 6":
RED 3" AND 6" WATERPROOF ALUMINUM EXTERIOR LED STRIPLIGHT BAR - Red - Exterior - Striplight Bars - Shop All Products (vleds.com)

Or, maybe a pod light?
RED MAX POD 8 LED WATERPROOF ALUMINUM EXTERIOR LED LIGHT - Pod Lights - Shop All Products (vleds.com)

Any ideas are appreciated! Thanks

 

Are you afraid of being bumped from behind?

I added a strobe to the 3rd light on my cap:

and added strobe backup bulbs:

Ya don't want to blind the driver behind you 'cuz then you will get bumped. All ya need to do is get their attention.

 

I’m liking your thinking! Maybe a strobe option would be good.
