Don’t want to add the other resistors until I know this is correct. Original board had no resistors and bulbs didn’t last. THANK YOU!

Some resistors are raised and soldered higher up on the LED legs.

You came to the right place for expert electronics advice

This is pretty basic for someone that is knowledgeable.

power and ground for the LEDs comes from the light green strips so the resistors wont do anything
AmonkeyK
also the solder looks like its shorting your circuit on a couple of the resistors

Thank you. What if I scraped some solder mask away and used SMD resistors between the LED legs?
bjlrr3000
Would scraping the copper and bridging the circuit with SMD resistors work?

I would leave the led's as they were and put one resistor inline between one of the power wires and its hole in the pcb
bjlrr3000
I thought for parallel resistors you need an LED per resistor?
SirRuppOfFigs
Voltage is constant in a parallel circuit. Let's say Vin is 12vdc. If you put in 6vdc the led's will be approx half as bright, yes?

Thank you.

Anytime

Btw, mind your wattage
