How do I choose an LED bulb for my car? Can I just put LED bulbs in my car?

LED headlight bulbs are steadily replacing halogen bulbs as the standard equipment in new vehicles – and they’ve become popular aftermarket upgrades as well. It’s easy to see why; the best LED headlights not only look great, they are also brighter, more energy-efficient, and longer-lasting than traditional halogen bulbs.

Are LED Headlights Road Legal?

The short answer is: it depends. Typically, fully legal LED headlight units come directly from the dealership when buying a new car, or as a factory-fitted upgrade. Factory fitted LED headlights are legal because they have been developed specifically for use in your vehicle and will not blind oncoming traffic. If you want to upgrade your halogen bulb to LED technology, it probably won’t be road legal.

But if you’re looking for an LED headlight upgrade for off-road use, then you’re going to need an LED headlight conversion kit. The best LED headlight conversion kits are completely plug-and-play and take most drivers 30 minutes or less to install. Just be sure that the LED conversion kit you get will fit your car; read the specs carefully, and if you have any doubts, ask the seller. The important thing is to ensure that the bulb is correctly installed and aligned properly to avoid distracting oncoming traffic.

How to Choose the Best LED headlight conversion kits for you

If you’re shopping for LED headlight bulbs, you need to consider factors like brightness, cost, lifespan, and ease of installation.

Compatibility & Ease of Installation

First, check the compatibility of your vehicle with the LED headlight bulbs. You can get the details of the size and type of headlight you need by checking your owner’s manual or your old headlight bulbs. Another thing to consider is the ease of installation. Some LED headlights have a simple plug-and-play design, while other LED conversion kits require additional tools like decoders and anti-flicker devices. You should also check whether they come with a warranty in case they stop working after some time. Some manufacturers will offer free replacements if this happens.

LED Light Bulb Lifespan:

While the average halogen bulb lasts between 1,500-6,000 hours, LED headlight bulbs can last anywhere from 30,000-60,000 hours (3-5 years). If you anticipate a lot of nighttime driving, go for the long-lasting LED headlight conversion kit brands like the Cougar LED Conversion Kit.

Brightness, intensity, and color temperature of your LED headlight bulb.

Typically a 6,000 Lumens headlight bulb with a bright color temperature between 3,500-5,000 Kelvins will do the job for most motorists. You can determine the brightness, intensity and color temperature of your LED headlight bulb by reading the product description. The brightness is measured in lumens (Lm), while the color temperature is in Kelvins (K).

Single Beam Vs Dual Beam Headlight

These bulbs have different wiring, so you cannot just swap them out without changing the wiring of your car.

Dual-beam headlight system

All vehicle headlights have low and high beams.  A bulb that performs both functions is referred to as a dual-beam bulb. So, each headlight will have one dual beam bulb for both the low and high beams.

Single beam headlight system

Single beam bulbs serve a single function, either high or low beams. So a single beam headlight system uses two headlight bulbs – one bulb for the low beam and another bulb for the high beam.
