I ordered these fires, not for me to use with position lights, but flashing reminder before on a Quad. It works fine, provided you connect them in parallel, not in series with the risk of "disturbing" flasher unit (in use of marker lights, you can connect them what you will) Product looks good, but a bit fragile (poor?). Indeed, one of the two broke during installation. Let me explain: You can buy them if they like you, but know before that we should not tighten them, at the risk of the small tubes mounting holes break! I glued with putty / white polyurethane adhesive on one side, and a small square crafted metal (also glued with the same product) on the other side. Apparently it holds, but it is not the "Top". I almost regret my purchase for another rectangular pattern slightly larger, Amazon sells more 1 pair, but who seems a bit more solid, and its attachment system and its seal. Not the ones I just bought! There. I hope these tips will serve you ...
