Before you Buy: White vs. Amber Off-Road Lights for your Truck?

The world of off-road lighting is absolutely massive, with a bunch of different companies offering dozens if not hundreds of different part numbers, and the sheer density of options makes it a nightmare to try to find out what will work best with your off-road rig. We talked before about the difference between Lumens and Lux, and Why Lux is more important, so now we're going to look at the difference between white and amber off-road lighting and which may be better for your truck. While neither one is inherently "better" than the other, white or amber may be a better bet depending on your climate, application, or how the rest of your truck's off-road lighting suite has shaken out.

Color and Color Temperature 101

Before we get into the differences between off-road light colors, we need to have a wee chat about what those colors are and how they're measured. All light color is measured on the Kelvin scale, which rates color from orange/amber to blue. In general, amber lights are lower on the Kelvin spectrum and generally sit somewhere between 2700K and 4000K white white lights are usually between 4300K and 6000K, with the vast majority at 5000K to 6000K. Kelvin ratings are helpful in figuring out where a given light lays on the spectrum of amber to white.

White Off-Road LED Lights

White off-road lights are by far the more common offerings in the off-road lighting world, and considering their benefits, it's pretty easy to see why. White off-road LED light generally gives you better range (though a lot of that is how your eyes perceive white vs. amber) and better general-purpose lighting than amber lights so that you get improved all-around visibility in most conditions. White lighting is great for job site use, dark forest roads with limited dust, dryer and warmer climates with limited amounts or no snow at all. White off-road lights do have a few downsides. Namely, they're not the best at actually penetrating dust or fog, and white light tends to reflect off of airborne particles far more than amber, which can have the opposite effect of what you want in snowy, foggy, or dusty conditions. Still, for getting maximum range and general forward lighting, white is your best bet.

Amber Off-Road Lights

Amber seems to be all the rage these days (especially in either fog or A-pillar mounts), and while some of that is for the aesthetic of just having amber or yellow lighting in those positions, there's more than a few reasons why amber can make for a good choice for at least part of your truck's off-road lighting suite. Despite your eyes not perceiving amber quite as well as white, yellow and amber lighting doesn't reflect off of airborne particles the same way white light does, which makes amber lighting excellent at penetrating actual fog, snow, and dust. If you're in an area with heavy snow or fog, or if you're in the desert where dust is an issue (like us here in Arizona), amber off-road lights are a great tool to help keep you on the trail. That being said, amber lights do have some downsides, and you probably don't want to make them your sole off-road lighting solution. The biggest downside of amber is that a lot of amber lights use amber or yellow lenses to get the amber look instead of just using amber or yellow diodes. The issue with this is that the color of the lenses of themselves add some opaqueness, which in turn, hurts overall output to at leas some extent. Thus, solely relying on amber for your entire lighting setup isn't always the greatest idea. Still, if you need dust, fog, or snow penetration, amber is a good way to go.

Which is better? Amber or White?

So with the differences laid out, which lighting color is actually better? The truth is that neither is inherently better than the other. Like anything, there's pros, cons, and nuance to the choice, and ideally, you'll be able to put a mix of both amber and white lights on your rig's off-road lighting suite. In general, it's best to cover all your bases if you can, and having a set of amber or yellow fogs or A-pillar lights certainly does look cool, while filling out the rest of your truck with white lighting will give you nice forward lighting capability.
