I've had an ultra light Pyro meter to my truck by a certified mechanic. I'm attempting to hook up the instrument lighting and realized it doesn't have a bulb assembly installed. Can I get a light for the gage?? Guess that's why it doesn't a white wire

Asked by: Keith64
Thank you for your question. This gauge should have come with a bulb and socket #3220 which installs in the back of the gauge and has one black and one white wire coming off. If your gauge did not come with a 3220 light, please contact our support team. You can reach them at 866.248.6357 or
