Worked excellently with what I had planned. Shipped right on time, product just as displayed.

These diodes worked exactly as advertised and were fairly easy to install. I installed at the nearest plug, by wiring additional connectors to each end to the diodes - that way I can remove them in the future and did not have to cut/splice wiring. CustomLED had great support to answer questions and assure me I was ordering the right parts. I would totally buy this product again, and will do business again with CustomLED the next time I need LED parts! I installed this, together with a blinker genie and relay - and I'm very happy with the entire set-up and the great customer service.
