1 light fixture with LED bulb for installation in the instrument panel of the Lancia Delta Integrale. This upgrade ensures that your gauges are clearly visible again in low-light conditions. The lights are compatible with the secondary panel featuring the oil temperature and oil pressure gauges with OEM part numbers 176299980 and 176585280. The lamp socket is easy to replace after removing the unit. Please note during installation: LED bulbs will only work if the positive and negative terminals are connected correctly. We have marked the positive terminal, which must always point upward when installing these bulbs in the instrument cluster. See also the included installation instructions. Always test to make sure the bulb works before closing the unit! With this light, the dimmer will still work just fine! So the light can be dimmed. This upgrade can always be easily reversed without causing any damage; simply put the original light with its base back into the recess, and the original setup is restored.
