Review on Partsam 10x High Power Blue T4.7 3-SMD LED Light for Automatic Heater Controls with Lamp Backlight Enhancement by Philip Brianne

Made three colors and a red, white and blue theme. That's great! The resistor is built in, so no additional resistor is needed for 12V clusters. Ignore any feedback that they don't work, they need to be soldered properly, both positive and negative. I just connected the disassembled cluster and put the LED on the contacts to understand how to install. If you're rough with the wires, they can come loose from the bulb, but they're easily soldered to the back of the bulb. These things emit light in all directions and illuminate the cluster so beautifully! There's just no other light bulb you want to use.
