How to convert Dome Lights to LED
Dome lights are problematic but they can still be converted to Safe low power LEDSince the bulb normally lies ‘sideways’ in the fitting. Most suppliers would offer you an LED ‘Tower’ bulb which in many cases will not fit and in all cases shines light backwards into the fitting where it can’t be reflected because the non transparent bulb blocks the light!
This is only for low voltage 12v or 24v lights found in boats or caravans - NOT suitable for mains voltage fluorescent lights!
If you don’t have a hot-melt glue gun you can use double sided ‘sticky fixers’ but in either case ensure enough height to allow air to circulate beneath – this helps to keep everything cooler and extends LED life!
