Choosing the Best LED Tail Lights: Your Complete Buying Guide
LED tail lights are a fantastic upgrade for any vehicle. They look sharp, last longer, and make your car safer. But with so many options, how do you pick the right set? This guide helps you choose the perfect LED tail lights.
Key Features to Look For
When shopping, focus on these main features. They tell you a lot about the light’s performance.
Brightness and Visibility
- Lumen Output: Higher lumens mean brighter light. Brighter lights help other drivers see you sooner, especially in bad weather.
- Light Pattern: Good LED lights spread light evenly. Avoid lights with dark spots.
Durability and Weatherproofing
- IP Rating: Look for an Ingress Protection (IP) rating of IP67 or higher. This means the lights resist dust and water very well.
- Lens Material: The outer cover needs to be strong. Polycarbonate lenses are tough and resist cracking from road debris.
Compatibility and Installation
- Plug-and-Play: The easiest options plug directly into your existing wiring harness. This saves a lot of time.
- Error-Free Design (CANbus Ready): Modern cars sometimes show an error message if you change the bulbs. Make sure the lights are CANbus ready to avoid dashboard warnings.
Important Materials Matter
The materials used determine how long your tail lights last and how well they work.
Housing Material
The body holding the LEDs is usually made of ABS plastic or aluminum. ABS plastic is common and durable. Aluminum housings handle heat better, which can extend the life of the LEDs inside.
LED Chips
The quality of the actual LED chips is crucial. Brands like CREE or Osram are known for high quality. Better chips produce clearer light and do not fade quickly.
Factors That Improve or Reduce Quality
Not all LED tail lights are made equal. Pay attention to these quality indicators.
Quality Boosters
- Heat Sinks: LEDs create heat. Good tail lights have built-in heat sinks (usually metal fins) to pull heat away from the chips. This greatly improves lifespan.
- Sealing: Quality lights use robust rubber gaskets to seal out moisture completely.
Quality Reducers
- Cheap Wiring: Thin, poorly insulated wires break down fast, especially when exposed to engine heat and road vibrations.
- Poor Lens Clarity: If the lens yellows or clouds up after a year, the overall quality is low. UV protection should be included in the lens material.
User Experience and Use Cases
Think about how you use your vehicle. This helps you choose the right style and function.
Daily Driving
For everyday use, focus on reliability and quick braking response. LED brake lights illuminate much faster than old incandescent bulbs. This small time difference can prevent rear-end collisions.
Off-Road or Work Trucks
If you drive on rough roads, you need maximum durability. Look for lights advertised as shock-resistant. Full sealing against mud and water is non-negotiable for these users.
Aesthetic Upgrades
Many people upgrade for looks. Modern LED designs offer sequential turn signals (lights that sweep) or unique light bars. Make sure the style you choose is legal in your area.
Frequently Asked Questions (FAQ) about LED Tail Lights
Q: Are LED tail lights brighter than regular ones?
A: Yes, generally they are much brighter. They turn on instantly, which gives the driver behind you more reaction time.
Q: Will installing LED tail lights damage my car’s electrical system?
A: If you buy quality, direct-fit LED assemblies, they usually will not cause damage. Cheap, universal bulbs might cause errors if they are not designed correctly.
Q: How long do LED tail lights usually last?
A: Good quality LED lights often last 10 to 20 times longer than traditional bulbs. Many are rated for 50,000 hours or more.
Q: Do I need a special flasher relay for LED tail lights?
A: Sometimes. If you only replace the brake and running lights, you might not need anything. If you replace the turn signals and they flash too fast (hyper-flashing), then you need a load resistor or an electronic flasher relay.
Q: What is the difference between LED replacement bulbs and full LED assemblies?
A: Replacement bulbs swap into your existing tail light housing. Full assemblies replace the entire housing unit, often offering better waterproofing and a more modern look.
Q: Is it hard to install LED tail lights myself?
A: Plug-and-play assemblies are usually very easy; they often require just basic tools and about 30 minutes. Always check the specific instructions for your vehicle model.
Q: Can LED tail lights cause condensation inside the lens?
A: Poorly sealed or low-quality lights can trap moisture. High-quality lights use vents to equalize air pressure, which prevents fogging.
Q: Are aftermarket LED tail lights street legal?
A: Most reputable brands meet DOT (Department of Transportation) standards for brightness and color. Always verify the product description says it meets DOT or SAE standards for street use.
Q: What is “hyper-flashing”?
A: Hyper-flashing is when your turn signals blink very rapidly. This happens because the car thinks the original bulb is burned out when you install low-power LEDs.
Q: Do LED lights work well in extreme cold?
A: Yes. LEDs perform very well in the cold. In fact, they start up faster in cold weather than traditional bulbs do.
