MARKER & SIGNAL LAMPS

Marker & signal lamps are a must-have for trucks and trailers, giving you visibility, safety, and keeping you on the right side of the law. They show the outline of your rig, signal your movements to other drivers, and make sure you’re compliant with road rules. At MaxiPARTS, we stock a wide range of marker lights and signal lamps across different voltages, colours, and functions, from LED marker lights to traditional halogen options. You’ll find trusted brands, single-function units, and truck side marker lights built to withstand tough Australian road conditions.

Why marker & signal lamps matter

When you’re hauling down the highway or backing into a dark yard, your LED marker lights are doing more than just ticking a compliance box. They highlight the full footprint of your truck or trailer, making it easier for other drivers to see you and stay out of your way. Side marker lights are convenient on long trailers or wide rigs, reducing blind spots and making night driving safer for everyone.

Types of marker & signal lamps available

We make it easy to choose the right parts with a range built for Aussie conditions.

LED vs halogen marker lamps

LED marker lights are designed to handle the tough conditions that trucks and trailers face. They last longer, use less power, and are less affected by vibration. Halogen lamps still get the job done if you’re after a quick replacement at a lower price, but LEDs are the smarter long-term pick for durability and performance.

Single function vs combination lamps

You can choose between single-function lamps that focus on one job, like a side marker, or combination lamps that roll multiple features into one unit, such as an indicator plus a marker. Combination lamps can save you space and wiring time, especially on modern rigs.

Voltages & electrical compatibility (12V / 24V)

Always match the lamp to your truck’s electrical system. Most heavy vehicles run 24V, while lighter trucks and trailers often use 12V. Fitting the wrong type can burn out the lamp or damage your wiring, so check before you buy.

Choosing the right lamp for your truck or trailer

When you’re picking truck side marker lights or signal lamps, consider:

• Voltage compatibility: 12V or 24V.

• Lamp type: LED for efficiency, halogen for budget swaps.

• Mounting style: Flush, surface, or bracket, depending on your vehicle.

• Colour and function: Amber for sides, red for rears, white for front-facing.

• Waterproofing: Look for IP-rated housings if they’ll be exposed to spray.

• Compliance: Lamps must meet Australian standards to keep you legal.

Installation & maintenance tips

Keeping your lamps in good nick isn’t hard, but it pays off:

• Wire lamps with correct polarity to avoid failures.

• Seal connections properly to stop water and dust getting in.

• Replace lenses that are cracked, faded, or cloudy; brightness matters.

• Clean lamps regularly with a soft cloth to keep light output strong.

• Inspect mounts and connectors during servicing to stop issues before they spread.

FAQs

What’s the difference between marker lamps and signal lamps?

Marker lamps make your truck or trailer visible, showing its size and outline. Signal lamps are for communicating your movements, like braking or turning.

Are LED marker lamps better than halogen?

Yes. LED marker lights are longer lasting, use less power, and handle vibration better, perfect for trucks and trailers.

Can I use 12V lamps on a 24V system?

No. Using the wrong voltage will cause the lamp to fail and could damage wiring. Always match the lamp to your system.

Are these lamps waterproof?

Many are sealed and carry IP ratings to handle water and dust. Always check the product details before installing.

Do I need professional installation?

Some lamps are plug-and-play, but proper wiring and mounting are key for safety. If you’re not confident, get a professional to fit them.
