AI Thread Summary
The discussion focuses on installing LED accent lights on a motorbike, emphasizing the importance of using a relay to prevent excessive current through the switch. Participants confirm that the general circuit design should work, but caution that relays can be complicated and require careful reading of data sheets. One user shares their experience of troubleshooting a non-functioning LED setup, which was resolved with help from an electrician due to incorrect wiring of diodes. It is highlighted that some diodes in the circuit were back-biased, preventing them from lighting up. Proper circuit design and attention to wiring details are crucial for successful LED installation.

Hello all i want to put some led lights onto my motorbike and i just wanted to know that this circuit is correct and yes I've drawn some leds the wrong way round. I want.to use a relay so that the current( even tho should be less than 1amp ) doesn't go though the switch although shoulnt really need it i think
Cheers
Tia

Yes, that general circuit should work OK.
 
Relays can be tricky. Read the data sheet and app notes carefully.
 
Thx i will
 
Me too added some blue LED lights on my bike. I did everything correctly but still it wasn't worked. After analyzing everything still unable to the find root cause of the problem and finally one my uncle who is senior electrician NJ helped me solve the problem.
 
In the wiring diagram, the group of diodes on the left will not light. They are wired "back to back", i.e. in each series pair one diode will be back biased regardless of applied polarity. The diode group on the right of the diagram looks fine.

It is noted on the circuit diagram.
