Thank you for your response. I don't know what an "hid's" is (similar to an led?). Anyway, I replaced the tailight/brake light bulb (not an led) but I did install an led illuminated wind restrictor last year (but the master light switch indicator did not indicate a problem then - only after the ordinary bulb burned out (which has since been replaced but the master light switch indicator remained illuminated even afterwards).

Any suggestion?

Thanks again.
