To change the instrument panel lights from red to white in a 2003 vehicle, you typically need to replace the existing bulbs with white LED bulbs. Begin by removing the instrument cluster, which usually involves unscrewing screws and gently prying it out. Once accessible, replace the red bulbs with new white ones, ensuring they fit securely. Reassemble the cluster and reconnect any wiring, then test the lights to ensure they illuminate correctly.
To access the instrument lights on an '83 El Camino, you need to remove the instrument cluster. Start by disconnecting the negative battery cable for safety. Then, unscrew the trim bezel around the dashboard, followed by removing the screws securing the instrument cluster itself. Once it's free, you can access the bulbs for the instrument lights and replace them as needed.
