I have tape lights that have worked perfectly for 6 years. They were wired into a switch and I have no idea if, or how a transformer was used. They are not on a dimmer. Even you you turn off the switch, the lights will continue to light/blink for a tiny bit.

  • Have you added LED bulbs somewhere else on the same circuit recently? – isherwood Aug 19 at 17:42
  • No. Someone was in to work on our oven but nothing else – PAULA LINE Aug 19 at 17:46
  • Barring any other changes, you may be seeing symptoms of device failure. – isherwood Aug 19 at 17:48
  • such as we need to replace the lights themselves? When people say the power source do they mean the switch?(wall receptacle box or something else along the circuit? – PAULA LINE Aug 19 at 18:14

Dead power supply

LEDs pretty much don't fail. Power supplies are the achilles' heel of LED lighting, and the primary reason why LEDs fail at all. (#2 being the lead-free [bad idea] solder crystallizing over some number of decades). Unfortunately people cannot resist making [read: buying] cheap power supplies.

You'll need to find this power supply unit, identify its voltage and current output, and get another one with SAME voltage and SAME OR GREATER current output.

If you want a hand with that, get a phone camera with a flash, and shoot a pic of the label on the thing. Then you can edit your question to add the photo.

If your LED's are more than 2 years old, blinking usually means that a circuit in the driver portion of the led lighting unit has failed. Things like this one usually cannot fix.

Best to buy new.
