who needs gauges and needles, go with your instinc.... j/k

There's several bulbs behind it, so one or two won't make it not visible, though it'll make yours look a lot dimmer. Anyways, what you mean by it's hard getting your needles to work right? Don't tell me you screwed them up? If you did, you prolly need a whole new electronic assembly, not just the needles and the gauges.
