• Brightness & Glare: Overly bright lights, especially those with improper beam patterns, can blind oncoming drivers, leading to dangerous situations and potential fines. Many states have restrictions on the number of auxiliary lights that can be on simultaneously on public roads.
• On-Road vs. Off-Road Use: Many powerful light bars and auxiliary lights are explicitly designated for "off-road use only." This means they must be covered or switched off when driving on public roads. Always research your local laws before installation.

2. Quality & Durability

You get what you pay for. Cheap lights may seem like a bargain but often fail prematurely.

• IP Rating: Look for an IP67 or IP68 rating, indicating excellent resistance to dust and water immersion.
• Housing Material: Die-cast aluminum housings are common for good heat dissipation and durability.
• Lens Material: Polycarbonate or tempered glass lenses are more resistant to impacts and scratches.
• Heat Management: LEDs generate heat. Good quality lights have efficient heat sinks to prevent overheating, which extends their lifespan and maintains brightness.

3. Power Consumption & Electrical System

Adding multiple powerful lights can strain your truck’s electrical system.

• Amperage Draw: Calculate the total amperage draw of all new lights. Ensure your truck’s alternator can handle the additional load without compromising other electrical components.
• Proper Wiring: Always use appropriately gauged wiring, relays, and fuses. A relay protects your switch and ensures the lights receive sufficient power directly from the battery, preventing voltage drop and flickering.
• Switches: Decide between standard rocker switches, multi-gang switch panels, or integrated control systems like SPOD or Switch-Pros for a cleaner, more organized setup.

4. Beam Pattern & Application

Matching the light’s beam pattern to its intended use is crucial for optimal performance.

• Spot Beam: Concentrated, narrow beam for maximum distance. Ideal for long-range visibility.
• Flood Beam: Wide, diffused beam for illuminating a large area at short to medium distances. Great for work lights or area lighting.
• Combo Beam: A combination of spot and flood, offering both distance and width. A popular choice for light bars.
• Driving Beam: A focused beam designed to complement high beams for on-road use (where legal).

5. Installation Complexity

Consider whether you’re comfortable with a DIY installation or if professional help is needed.
