A Guide to Different Types of Truck Lighting and Their Replacement Parts

Trucks’ Lighting systems are paramount to ensure a safe driving experience, especially during night-time or low visibility weather conditions. They are essential for the driver’s visibility and signal other motorists about the truck’s presence and intentions.

This truck lighting guide will explain the various types of truck lighting and discuss appropriate replacement MAN truck parts in case of failure or damage.

1. Headlights

Headlights are the primary illumination source for night-time driving and poor weather conditions. These typically come in two variants: low-beam headlights (dipped beam) and highbeam headlights (main beam).

The low-beam headlights cover a short range, providing light directed at the road surface to avoid glaring other drivers. In contrast, high beams provide long-range illumination in low-visibility conditions.

Replacement bulbs for headlights vary depending on the specific type installed – Halogen, HID (High-Intensity Discharge), or LED bulbs. The parts number will be stated within your vehicle’s operating manual, but the most common are H7 and H4 for Halogen and D2S/R for HID bulbs. One of the most popular brands for replacement headlights is Hella, renowned for its high performance. Hella is an OEM (Original Equipment Manufacturer) for many European truck brands such as MAN, Daf, Scania, Iveco, Mercedes and Volvo. Trusting in such recognised OEM brands helps ensure quality and compatibility with your vehicle.

2. Tail Lights

Tail lights, also known as rear position lamps, provide visibility to the truck’s rear. They signal other motorists about the truck’s size and shape in low visibility.

Tail light bulbs usually operate on the same switch as the headlights. When replacing tail light bulbs, consult your MAN truck’s parts manual for the correct bulb type and size.

3. Brake Lights

These are red lights at the rear that illuminate brighter than the tail lights when the brake is applied. They signal other motorists when you’re slowing down or stopping.

When replacing brake light bulbs, choose the correct type as indicated in your vehicle’s manual. Once identified, you can look to Narva, which offers a wide selection of truck and trailer rear lighting solutions.

4. Turn Signal Lights

Turn signals or indicators flash to indicate the direction of the truck’s turn or lane change. They are present both at the front and the rear.

Replacement of turn signal bulbs usually involves removing the light lens cover and changing the bulb. Amber-coloured bulbs are primarily used for turn signals.

5. Fog Lights

These are designed to cut through adverse weather conditions and provide better visibility during fog, snow, or heavy rain. They typically have a sharp, low, and wide beam.

Some examples of types of fog light bulbs include  White or Yellow H11 LED, 9006 LEDs, H3, and H10. Consult your vehicle’s manual to pick the correct bulb.

6. Auxiliary Lights

Auxiliary lights, including LED light bars, work lamps, beacon lights, and spotlights, give extra illumination for large vehicles like trucks, especially in off-road circumstances.

Auxiliary light replacements will depend heavily on the make and model of the light you have in place. Traditional halogen bulbs, HID lamps, or modern LEDs may be needed.

7. Marker Lights

Marker lights, also known as clearance lights, are amber or red lights positioned at the truck’s front (amber), side, or rear (red) to indicate its dimensions.

It is advisable to consult your MAN truck’s manual or seek advice from a vehicle parts specialist when replacing any light to ensure accuracy and compatibility.
