Discovery 3 LED trailer lights

You can reduce this heat by using a 25w 6.8ohm resistor instead of the 50w units.

My next batch will be tested using these.

Ok guys this post is probably up there for Dumbest post of the year, but bear with me please. [bighmmm][bighmmm]

After reading all 331 posts thee times, I'm not clear on one aspect or I've confused myself [bigwhistle]

I get that the load resistor connects one end to either indicator wire and the other end to earth to create a parallel circuit, but where in the circuit does it connect?

1. Before the indicator wire
2. After the indicator wire
3. Somewhere in the trailer plug wiring in the vehicle

Thanks in advance for any clarification

Cheers
John

Branches off of the indicator circuit at any point prior to the LED assembly at the other end.

Thanks Tombie, much appreciated

Cheers
John

Or after the LED assembly. The electrons don't give a **** as long as they have a road to travel on.

Yep. Thats the next lot I'll be testing in my rig.

I build them in spare moments.

Got any D4 setups for sale? I'd prefer one hardwired into the vehicle with a switch.

Just received a pair of these. Much smaller/ much less bulky than the original suggestions, so hopefully up to the job?
