Check the listing for details. Speedo Gauge Bulbs to White LED Upgrade Package DIY for GM Trucks and SUVs 03-06. Condition: New. Listed at 18.99 USD. Gauge cluster bulb replacement kit with white LEDs. Our Kit contains 12 Cube LEDs, needle removal tool and detailed instructions with pictures. LEDs were specifically designed for 12 volt instrument clusters and do not require a resistor as they are built in. 12 LEDs total: 9 for the back lighting, 2 for the blinkers and 1 for the cruise control. LEDs dim up and down just like normal bulbs. This cube-shaped LED emits light 360° in every direction. It's simple to solder these surface-mount devices to the circuit board in your gauge cluster once it's out of the vehicle. You will need to remove your stock incandescent bulbs and solder these on the circuit board. Installation time is about 1 hour. We also have LED Kits for your climate control, steering wheel buttons, and a kit for the switches on the left side of the dash. They are the same LEDs as this kit so all colors will match.
