【Brand New】Glow plugs for fluorescent lights. If your fluorescent light starts flickering, it's a sign that the glow plug is wearing out. If you continue to use a worn-out glow plug, it can damage the fluorescent light itself, so you need to replace the glow plug if it flickers. A set of 2 glow plugs, convenient to have in stock. Both are unused. I am selling these because I switched to LED lights and no longer need the glow plugs I had in stock. If you purchase these together with other items I have listed, you can get a discount from 300 yen to 100 yen. If you would like to use the combined discount, please be sure to inform me of the items you wish to combine and that you would like the discount in the comments before purchasing. Thank you. #IfFluorescentLightsFlicker #GlowPlug #FluorescentLightGlowPlug #FluorescentLightGlowPlug #GlowStarter #Starter #FluorescentLightFlickering #FluorescentLightFlashing
