Using suction cups from Uncle Bezos and a piece of 1/8 x 3/4 aluminum bar stock, I made a very workable prototype with another to follow.

Very happy with the results !

Are you taking orders? That is a really nice job on the bracket!

Jacques:

Thanks very much for posting your brake light design. Looks great. I would like to make one for the 40 Ford split rear window so there is a light on each side of the window divider bar. WELL DONE.

I think you meant BIKE SPARK.

Please post the site where you bought the suction cups.

Suction cups were bought on Amazon, “Pawfly” 30 pack in various sizes; the 1.2” is the Goldilocks size and can be purchased without the others. Wasn’t sure for the first run, but 2x 1.2” are more than enough.

Happy to supply brackets for anyone who needs one for cost of postage and a small donation to www.whistlepigrescue.com in the amount of your choosing .

I like this idea. But for use on my pickup, I might make one with strong magnets to go on my tailgate.

The Bike Spark light seems like a very good product, with stated recharge intervals of as long as 3 months. I’ve bought several for this project.

I just ordered one. I'll post it after I make the tailgate magnet mount.

[Jacques1960]

Excellent !

The bike spark arrived today. Is it normal for a dim light to be on in mode 1, then go to bright on decelaration? I assume it is, I just thought it was a brake light only. I have it charging now. Will work on the magnet mount tomorrow.

I had a school bus stop light as a 3rd brake light. This is in my opinion the best way for a pickup

Yes, and upon braking there are at least two options - one a steady brake light and the other a strobe.

If I recall correctly, the charge interval is one month in “steady” mode and three months in “strobe”,

Magnetic mount finished. It was easy to do using two Harbor Freight magnet hooks for the magnets.

Neat idea! Cover the magnets with saran wrap to protect your paint.

I put a layer of clear packing tape on them to prevent scratching. Works perfectly!

[Jacques1960]

They look great - and NO wiring required !

Jacques,

The bracket looks very professional. Nice job. Now I just need to order the BikeSpark G4R from Amazon. I see there are a number of different models of BikeSpark. I will make sure to order the G4R model you called out in your 9-2-22 posting that has the mounting fasteners at 80 mm.

Thanks again,

JimG

Thank you Jim; let me know if you ever need additional suction cups. Note that you will want to clean glass before installing for best results.
