Bits and pieces are coming together to build the lights and fenders for the Sprint-T, in the form of a turn-signal/marker light that can be mounted over or under the headlights on the backing bracket for the buckets that hold and aim the headlights. It’s not much, just a strip of amber LEDs in a weatherproof housing with a 3 wire hookup, ground, high, and low light output to cover all the functions the light has to perform.
How I hook the lights up depends on how the low and high outputs function. If high power overrides low power inputs then I will drive around with the low power and ignition switch on the same inputs, but the other way around, low power overriding the high power input I have DRL and I connect the turn signals to the low power to make them blink at low power and cause the DRL to flash. It all depends on how the light reacts to inputs. And to know that I had to buy a power supply and test leads. My old 12V power supply burned out about a decade ago when I was building high-output bike lights and taillights, and apparently my test leads went with it in the trash. The new power supply is big enough to test all my 12V lights, just not at the same time.
I bought other 12V power supplies/battery chargers between when my previous one burned out and now, but they only function/supply power when there is a 12v SLA battery connected to the outputs unlike the previous versions I bought. And I no longer have any 12V SLA batteries I can plug into the circuit, if I did I wouldn’t need to buy another power supply. Fortunately this power supply is built to support large chains of LED lights, or higher power LED spotlights or landscape lights. It will power one of the headlights, but not all 4 of them at one time. The 5A limit will only handle one headlight. But I just need to test one light at a time.
