Why Motorcycle Neutral Light Not Coming On- How to Troubleshoot

Even while it may seem natural for you to replace the neutral light on your motorcycle if it breaks, this may not be the best course of action in this scenario. Many complications might cause issues with motorcycle neutral lights, including damaged wiring, bulbs, and connectors, to mention a few. It is vital to troubleshoot the motorcycle neutral light to narrow down the number of possible reasons for it.

There are three possible reasons why your neutral indicator light is not working. For starters, the indicator’s bulb is not working correctly. The wires have disconnected two, the transmission’s neutral switch. Alternatively, the transmission’s neutral indicator switch may be faulty. Consider the chrome cover that sits atop the transmission on the right-hand side of the motorcycle.

Having a motorcycle neutral light that does not function properly can be dangerous on the road. This section contains in-depth instructions on how to troubleshoot a failing neutral light and maintain the light after it has been repaired or purchased. In addition, you can find commonly asked questions and answers on this page. You will have gained a great deal of knowledge regarding neutral lights as a result of this.

Step 1

The neutral light should be removed first, and then you may continue with the rest of the processes. A connector is positioned behind the motorcycle’s neutral light in the rear. It is necessary to follow the cable heading to the plug. During the journey to the wiring loom, keep a watch out for any damaged or exposed pieces of wire.

 Step 2

The plastic parts around the plug and bulb for the neutral lights should be inspected for damage or wear. It is necessary to repair the damaged pieces if you notice that the plastic has been scorched or the connections have become filthy.

Step 3

For damage indicators, such as blown fuses, inspect the bulb closely. The power source for the motorcycle’s neutral light will be damaged if any items are present.

 Step 4

Count how many watts are being consumed by the light bulb at this point. Consult your motorcycle manufacturer’s instructions to ensure that the bulb wattage of the motorcycle neutral light is the proper type for your bike. The wattage of the bike’s headlamp will be shown on the vehicle’s back bumper.

 Step 5

Check the operation of the motorcycle neutral light relay to ensure that it is working correctly. There may be an issue with the relay if the light does not always come on when the bike is started. Removing the relay and replacing it with a known-working relay would be enough to repair the problem with the motorcycle neutral light in this situation.

Using a voltage meter, check the voltage of the motorcycle battery. If you find that the neutral light fuses are constantly breaking or that the neutral light is frequently dimming, you should use a voltage meter to test the voltage level in your vehicle.

To address this issue, the burned-out bulb must be changed. Before returning the lamp to the manufacturer, it is necessary to properly inspect the electrical connector on the back of the light for any damage. Verify that it is not loose or rusted, and if it is, get it replaced with a new one. Most of today’s vehicles have neutral light bulbs that are replaced through the chassis at the rear of the vehicle. It is possible to drive right up to the housing unit in some cars.

 In some cases, it may be more complex because you will have to remove numerous components to make access more difficult, but it may be more straightforward in others. Depending on the situation, you may be required to remove the housing’s mounting nuts to remove the entire chassis before performing the bulb change. The particular directions for replacing neutral light bulbs should be double-checked in your owner’s handbook, which you can find in your owner’s manual.

As soon as you have removed the socket from the housing, you should immediately pull out the old bulb and replace it with a new one. Please remember that the replacement bulb should be the same size and style as the old one, which is extremely important to keep the light working correctly.

Choose from a wide choice of aftermarket solutions when it comes time to replace your bulb. To improve your car’s overall performance, you might select neutral lights with a more excellent wattage rating. As a result of the improved performance, vision in inclement weather and at night will be much improved. It is not suggested that you touch the glass of the new bulb with your fingertips, but it is possible too.

That’s because your fingertips are coated with oil, which might harm the glass, resulting in the glass burning before its time. A plastic base should be used to hold the bulb during installation, which can be held in place using a cloth, tissue, or gloves if the bulb is fragile.

Before returning the bulb to the enclosure, it is required to test it in the socket after being placed there. You should switch on your neutral lights so that you can see if the bulb has been lighted yet. If the light was on, it meant that your connection had been successful.

After this step is done, the socket and bulb can be reinstalled in the housing. It is necessary to rotate the socket in the right direction before being locked into place. Failing to do so will result in dirt and water trying to find their way into the housing, which will eventually cause corrosion to develop.

A damaged or loose socket could cause the failure of the replacement headlamp to illuminate. The likelihood of a wiring problem in the neutral light circuit has also been raised in the past. – It is possible to acquire an aerosol electronics cleaner to treat socket rust, which should be sprayed into the socket to eliminate the problem. However, if this does not cure the issue, it may be essential to replace the socket altogether. Dielectric grease can be applied to the socket before installing the bulb to prevent damage.

Identifying and troubleshooting neutral light problems on a vehicle

Identifying and troubleshooting neutral light problems on a vehicle

The following are the steps to diagnose a truck’s neutral light:

Step 1

Ensure that your neutral lights are functioning correctly. Before determining which neutral lights are not working, ensure your Ranger’s motor is running, and the neutral lights are turned on. If your neutral lights operate but flicker, it is likely that the problem is caused by a faulty or broken neutral light switch. The assistance of a specialist to fix the damage will be required. It is most likely that a faulty bulb or relay is to blame if only one of the neutral lights is not working.

By turning on the high-beam neutral lights, you can see how well they work. If your high beams work, but your low beams don’t, it’s most likely due to a faulty bulb or relay (or vice versa).

Step 2

Check the bulbs for corrosion or deterioration. Once the bulb sockets have been removed and positioned to the rear of the neutral light assembly, the filaments should be checked. If the bulb is malfunctioning, the filaments will be broken; the filament will be attached if the bulb is in good operating order. Replace the bulbs if necessary. If you don’t know how to identify a broken bulb on your own, you can discover samples of “good” and “bad” bulbs under the Resource section.

Step 3

A multimeter can be used to check if the neutral light relays are operating correctly. The technique for inspecting the relay will be determined by the type of relay used and the number of coils and switches in the relay. The use of a multimeter should be left to the professionals, and only after you have checked out, all other alternatives should you contemplate replacing the relays. Before replacing the relays, check to see that they are in proper working order and that all possible faults have been ruled out.


It is essential to fix neutral lights and any other faults that may emerge. Understanding and applying the information in this article will help you solve various neutral light-related issues.

Whether using high or low beams, superior neutral light solutions should offer broad road lighting.
