Are you talking about specific kinds of leds?
A $15 rgb strip is as good as a$100 strip most of the time(ie superbright led)
for forward facing lights, the cheap amazon lights have a hue that is very white, and a lot of lumens, but, they are woefully poor in reflector tech. They’re also limited lifespan, most leaking at about 1-2 years. That’s not to say they’re useless, they’re not. If you need to save a few pennies, get a really decent wiring harness no matter what, so you minimize the time you spend going back behind the job to replace them with better lights.
I know several of the lighting vendors here will be glad to help you out.
First things first: What are you going to use the lights for?
aesthetics / starbucks posing?
street use only?
street with some off roading.
Off roading, possibly at night, maybe some street usability
The lights typically put into the bumper slots where you see kits can and often do have SAE lights included, and that’s a good choice for additional street lighting that’s legal. I’m familiar with the Baja Design lights; wide corner, combo and spot. combo is half of wide corner and half spot.
Wide corner squadron pros are the bees knees for throwing light everywhere in front of your truck, but not very far. These were the last ones I added and the ones I ended up really liking the most. I’m currently running 2x spots, combos and SAE, but I’m probably going to go to 4x combo, 2x SAE. I don’t think the spots contribute much in the bumper position.
If you’re looking for more, the S8 behind the grille kit is pretty awesome, pushes past to midrange distance. For long range I added a set of xl80 spots with hood mounts.
Is there a noticeable difference? I’ve had both Amazon sourced LEDs and B/D lights I needed financing options for. The BD are just better, period. Reflectors are much higher quality, beam cohesion, water proofing... everything about them is just better.
You get what you pay for.
Others on here run Rigid, some KC, and a few others and I’ll defer to them on their quality. Most input I’ve seen has been positive.
Catch up with one of our lighting vendors and they’ll set you on a path to spending lots of money for lots of lumens...
