My flashlight flickers, what should I do?

Flashlight flickering is almost always caused by dirty battery contacts that build up with time. To solve this problem you will need to clean the center contact on the LED module or bulb, along with the positive and negative contacts on each battery. Use a mild abrasive (steel wool, emery board, Scotch-Brite® , or even plain paper) to remove dirt and corrosion, and then wipe the contacts clean with a paper towel or coarse rag.

Sometimes flickering is caused by dented batteries, which can happen if you drop your light. Inspect the positive (+) end of each battery for dents and dimples. If minor "dimples" are found only on the tips, try placing an undimpled battery on top of the stack. Replace the battery If the whole top is dented in.

If there is liquid or black discoloration inside your light, see the My batteries leaked, what should I do? FAQ.

Warranty returns for flickering will always be cleaned and returned; however, you can save the shipping costs both ways by performing this simple procedure yourself. Leaking or damaged batteries are not covered by warranty.

My batteries leaked, what should I do?

Flush out case with warm fresh water. Dry thoroughly. Remove and dry off battery contact strip and/or bottom battery spring. If spring is discolored or corroded, clean with steel wool or light grit sandpaper. Check lamp contacts on bottom of reflector, clean if discolored or corroded. Reassemble with fresh batteries and test. If it still doesn't work, return the light to us.

I replaced the batteries but the flashlight still doesn't work. What should I do?

Check battery and bulb contacts for discoloration or corrosion, clean if necessary. Try replacing bulb. Make certain the replacement lamp is correct for your light model (labeled on lamp; 1.2 V = 1 battery, 2.4 V = 2 batteries, 3.6 V = 3 batteries, 4.8 V = 4 batteries, 7.2 V = 6 batteries). Remember, the Mark-Lite® Fire Fly™ requires 2 - N alkaline batteries, not 1 - AA battery.

What are LEDs?

LEDs are Light Emitting Diodes. Diodes allow electric current to flow in one direction; LEDs are also diodes, but they also have the unique "side effect" of producing light while electricity is flowing through them. The advantages over traditional bulbs are as follows:

  • Reliability - 10,000+ hour rated life
  • Durability - Vibration and shock resistant with no bulbs or filaments to break
  • Cost Savings and Convenience - No bulbs to change? ever!sm
  • Energy Efficient - 1/5 the energy consumption of standard lamps
  • Natural Light - Emits light color similar to the sun
  • Safer - Solid state lamps make LEDs safer in hazardous environments
