I have had the same issue with my 86 IP 31. I removed the light and cleaned the switches painted the reflectors a flat white and replaced the bulbs with LED s from Superbright LED an on line vender. The bulbs were single contact in the 2700 range. I am very happy with the results. Cost , amount of light and power needs to light up the interior..
