Learn How to Repair Broken E-Bike Lights

If your eBike’s lights have stopped shining, there’s no need to fret. Keep reading to learn about the process of light repair.


Follow these steps for the quickest way to repair broken lights on your electric bike.

  1. Check the BatteryYour e-bike’s battery is one of the most important components of the whole system, and it’s also responsible for powering any of the lights installed on your bike. Your first step is to check your battery to ensure it is still providing enough power to your lights. If your e-bike works and gives you normal performance, then your battery is likely fine. However, if you’ve noticed performance drops, you might have a battery problem. You can test the battery using your multimeter. Connect the multimeter to the battery and choose the “test load battery” option. You should also check voltage, current, and resistance. Compare the results with the specs from the manufacturer. If you have a bad battery, you’ll likely need to get it replaced.
  2. Check Your Connections
    If your battery is good, you may just have a bad connection between the battery and the light. This can happen over time as you use your e-bike, especially over rough terrain. First, check the connections on the light and press them in to make sure they are tight. Next, you’ll want to check the connection where the lights plug into the bike. These connections are usually housed in the pedal assembly. To open the pedal assembly, you’ll need to use a combination of different tools that may vary depending on your e-bike model. Usually, you’ll need a combination of Allen wrench, flat head screwdriver, and Phillips screwdriver. Make sure you keep track of all screws and bolts so you can put the assembly back together again. After the pedal assembly is opened, check the connection to ensure it is tight. If it isn’t, press it back into place.
  3. Check for Wiring Damage
    While you have the pedal assembly open, you can also check the quality of the light’s wiring. Visually inspect the wire for corrosion or damage. If the wiring runs through the frame, you may want to disconnect the wire from the bike and pull it out of the frame to inspect its full length. If the wiring is bad, it’s usually much easier and cheaper to replace the entire light.
  4. Replace the Bulbs
    If you have an incandescent or halogen bike light, you may just be experiencing a burned-out bulb. This can happen over time, so if you’ve had your lights for a long time, this is a likely suspect. Remember that LED bulbs should not burn out very often.
  5. Replace the Entire Light
    If you can’t figure out the problem, then your eBike’s light may just be bad and need an entire replacement. You won’t need to purchase the exact same light for a replacement, so you can use the opportunity to shop around for a new product.
  6. Take the eBike to a Repair Shop
    If you’re not comfortable opening up and repairing the bike’s lights on your own, or you simply can’t figure out the problem, then you can always take it to a certified repair shop. Look online to find a repair shop near you, but make sure to find a highly-rated option so you can get the best service and prices. Once you’ve found a reputable shop, give them a call to get a quote on how much light repair would cost. If you’re happy with the service and pricing, set up an appointment or just take your electric bike in at your earliest convenience.
