How to Put Lights on a Dirt Bike Without a Battery?

how to put lights on dirt bike without battery

When it comes to off-road dirt biking or motocross racing, proper lighting is essential for safety, especially at night. Many dirt bikers come equipped with batteries to power their lights, but alternative methods exist to put them on a dirt bike without a battery.

Dirt biking is popular for its challenging off-road terrains. If your dirt bike doesn’t have headlights and taillights, you may find some difficulty in your sports at night. It would help if you had lights on a dirt bike to enlighten it when it’s dark outside. 

Putting the lights on a dirt bike without a battery is an essential skill to be learned for any off-road rider. It seems a difficult task, but with our guide, you’ll know how to put the lights on your dirt bike without a battery and the tools you need during this process. 

In some states of the U.S.A., dirt bike riding is street legal according to laws. But to make a dirt bike street legal, you must install a headlight first. We’ll present simple tricks to make your light installation easy and affordable.

Is it Possible to Put Lights on a Dirt Bike without a Battery?

A.C. is converted to Direct Current (D.C. power) using a rectifier. The rectifier is mounted near the magneto.

D.C. power can be used to power the lights on the dirt bike. The lights will need to be wired to the rectifier and the switch. The switch will allow you to turn the lights on and off.

Use L.E.D. lights, which are more efficient than simple lights, so that they will use less power from the magneto. It’ll help to prevent the battery from draining too quickly. However, even without a battery, you can still install lights on your dirt bike. It uses alternative methods that draw power directly from the bike’s engine.

Can you Start a Battery-less Dirt Bike?

A dirt bike requires an electric start if the battery power is good. But you can’t start a dirt bike when it has a dead battery. However, some methods are here to start your dirt bike engine without a battery.

1. Kickstart mechanism

 It’s possible to start the dirt bike using the kickstart lever, bypassing the need for a battery. The kickstart lever allows you to manually kickstart the engine with your foot to turn the crankshaft and initiate the combustion process.

2. Push start

To do a push start, you must find a hill or other incline to start the bike on. Put the bike in gear and hold the clutch lever in. Then, push the bike up the hill until the engine starts.

3. Bump start

Bump start requires a helper to hold the bike upright while you sit on the bike and turn the throttle. Then, have your helper push the bike forward. The compression from the engine will help to start the bike.

Tools to Consider Before Putting Lights on Dirt Bike

The tools needed for light installation are the most important things you must consider before putting lights on a dirt bike. So, you’ll need proper tools‘ for lighting your dirt bike. Before starting the installation of lights, it’s necessary to raise or lift your dirt bike well enough to avoid any accidents. Safety comes first!

Here’re all the essential tools needed to put the lights on a dirt bike without a battery:

1. Insulated Wires

Insulated plastic-covered wires are necessary for well-connected lights in your dirt bike. The power supply from these wires will help the headlight to switch on immediately. Different colors of wires are available in the market to differentiate their functions. Purchase the yellow, red or blue colored wires to identify the negative or positive of wiring in the future. 

2. LED 12V Spotlight

No other tools are necessary other than an L.E.D. spotlight. You’re mounting a spotlight on your dirt bike. Therefore, choose an L.E.D. 12V spotlight for your dirt bike with efficient brightness, durability, suitable mounting options, and power consumption. Look for reputable brands and read reviews to ensure quality and reliability.

Try to mount the light in the middle of the dirt bike, not even too low or too high. So, place it at the appropriate height. 

Do You Know?

An electrician to install L.E.D. lights will generally cost between $200 and $250 per fixture. 

3. Bolts

Bolts are used to tighten the lights secured and fixed in place. So that if you run the dirt bike fastly, the lights remain fit in their places. 

4. A Pair of Pliers

A pair of pliers is essential to properly cut the ends of wires and connect them to gadgets or other poles. I’ll not recommend using your strong teeth for cutting the wires, as people do the same often. It may hurt you. Therefore, keep pliers with you when putting lights on the dirt bike. 

5. Spanner

Spanner is a versatile tool for its functions. It’s used to unmount and remove the seat and gas tank. You should keep every size of spanner with you. Spanner works to tighten the nuts and bolts while mounting the seat and gas tank.

6. Driller

A driller is used to make holes to pass the wires from the walls, making them look tidy. Drillers can make a professional look at holes. 

7. Rectifier

The rectifier is a valuable tool. Utilizing this device, you can change the alternating (A.C.) power supply into 12V direct current (D.C.).

8. Bullet Connectors

Bullet connectors are a type of electrical connector that is used to join two wires together. They’re popular for dirt bike lights because they’re easy to use and provide a secure connection.

Bullet connections have a male connector shaped like a bullet and a female connector shaped like a socket. These are used in automotive connections of wires. 

9. Electrical Tape

Electrical tape is useful for insulating and securing wiring connections when installing lights on a dirt bike. It protects against moisture and secures the wiring in place.

10. Zip Ties

Zip ties are versatile for securing and mounting the lights on a dirt bike. They can organize and secure wiring and mount lights to various bike parts.

11. Double Handlebar Switch

You don’t want to remain your dirt bikes light on for extra time, right? The double handlebar switch will help you easily turn the lights on and off when needed. 

Why it’s called “Double“- because it allows you to switch ON and OFF for L.E.D. spotlights; the switch should be placed so the rider can access its reach.

Types of Lights To Put on Dirt Bike

When choosing lights for your dirt bike, several types are available, each with features and benefits. Here’re some common types of lights that you can consider:

  • L.E.D. Light Pods
  • Auxiliary Lights
  • Headlights
  • Light Bars
  • Brake and Tail Lights
  • Turn Signals

Which lights should you get for your dirt bike? It would be best to have a front headlight and a rear taillight for your dirt bike. The headlight is front facing light that illuminates the road ahead. At the same time, the taillight is a rear-facing light for the other drivers to see you. Your front light should be bright enough to observe all the upcoming obstacles.
