These bulbs are brighter, but are very sensitive when installing in the gauges. I bumped some wires installing them in the lower gauges where there's not much room to snake the bulb back into the gauge. If you bump and knock out one LED the whole bulb quits working as they are wired in series. Be sure to order a couple extra.
Lumens (Max) 40 Lumen
