When the light bulb in a shower ceiling goes out, many homeowners assume they will grab a stepladder and quickly change out the bulb. They often are surprised by the confusing recessed lighting fixture with which they come in contact. If you've never seen a light fixture that works with torsion springs, you may not be able to easily discern the correct route to the light bulb. No visible screws exist and the clear cover over the bulb doesn't budge when you poke it. Changing the light bulb in a torsion lighting fixture is a simple process once you know how they work.
Turn off the shower light at the light switch.
Place a rug with a rubber backing in the shower stall to keep the stepladder from sliding. Place the stepladder on top of the rug.
Insert a metal putty knife between the outside rim of the light fixture and the ceiling. Be careful not to scrape the finish off the ceiling when inserting the putty knife.
Pry the fixture cover from the ceiling with the putty knife. The fixture cover includes the clear plastic covering in the centre and the metal rim. The cover is held in place by torsion springs, so it will be resistant to release. Apply pressure until the cover pops off the ceiling.
Change the light bulb.
Press the cover back in place. The torsion springs will click into place when you press the cover into the ceiling.
Wear safety glasses to prevent dirt and debris from falling into your eyes.
