Upgrade your turn signals and brake lights with NLpearl’s dual‑COB LED bulbs. Instant full brightness, 360° beam, and aviation‑grade cooling deliver 30,000 hours of safety‑blazing light.
Super bright COB chips with instant light and superior heat dissipation for maximum driving safety
Solves
- dim original bulbs reducing visibility
- delayed light activation creating safety risks
- overheating causing premature bulb failure
- poor heat management in compact spaces
Instant Blinding Brightness for Safer Driving
Replace slow, dim stock bulbs with NLpearl’s COB LED technology. Experience 360° light that cuts through night and weather—no delay, no dimming, just reliable visibility.
Three Layers of Protection
Convex Lens Flood
A precision‑curved lens captures every lumen and projects it evenly across the reflector. No dead spots, no shadows—just uniform, blinding amber light.
Twice the Punch
Two high‑output COB chips fire simultaneously, delivering a peak brightness that rivals daylight. Even in direct sun, your signal is unmistakable.
Fan‑Driven Chill
A miniature fan pulls heat away from the chips and through aviation‑grade aluminum fins. Temperatures stay low, so the bulb stays bright for 30,000 hours.
Performance Without Compromise
- 30,000hrated life — 20× longer than halogen
- 360°uniform beam, no dark spots
- 0.1sinstant full output — no warm‑up
- 15°Ctemperature drop vs. conventional LED
Install in Five Simple Steps
- 1Turn off the vehicle
Engine off, lights off. Give the bulb a few minutes to cool if it was recently used.
- 2Access the bulb housing
Open the trunk or hood and locate the tail light assembly. Remove the access panel or twist the socket counterclockwise.
- 3Remove old bulb
Gently push in and twist the old bulb counterclockwise, then pull it straight out.
- 4Insert NLpearl LED
Align the pins, push the LED bulb into the socket, and twist clockwise to lock. Do not touch the LED chip with bare fingers.
- 5Test and reassemble
Turn on the ignition and activate the signal or brake. If it lights instantly and brightly, reinstall the housing.
From Flickering to Flawless
The Problem with Stock
Factory bulbs are slow to light, dim after months, and generate heat that shortens their life. In rain or fog, they fade when you need them most.
Engineering the Answer
We paired dual COB chips with a convex optical lens and aviation-grade aluminum. The result: a bulb that stays cool, lights instantly, and fills the housing with light.
A Safer Drive, Every Time
With 30,000-hour lifespan and instant full brightness, your turn signals and brakes become impossible to ignore. No meltdowns, no delays, just pure safety.

Questions and answers
Will these cause a hyper‑flash or error on my dashboard?
w
Wanelo · seller
Most modern vehicles will not hyper‑flash thanks to built‑in resistors, but some sensitive CANbus systems may need an external load resistor. We recommend checking your vehicle’s bulb type compatibility. If hyper‑flash occurs, a resistor kit sold separately will fix it.
Are they truly brighter than my stock bulbs?
w
Wanelo · seller
Absolutely. Dual COB chips and a convex lens focus and disperse light far more efficiently than a filament. Users report being clearly visible even in direct sunlight and heavy rain.
How long will they last?
w
Wanelo · seller
The aviation‑grade aluminum and integrated cooling fan keep the chips well below their thermal limit, allowing a rated life of 30,000 hours. That’s over 20 times the life of a typical halogen bulb.
Do they fit my car?
w
Wanelo · seller
They come in multiple socket types — BA15S (1156), BAY15D (1157), and BAU15S (PY21W). Check your owner’s manual for the correct bulb type before ordering.
Is the fan noisy?
w
Wanelo · seller
The fan is extremely quiet and operates only when needed. In a moving vehicle, you won’t hear it at all.
Why are these more expensive than generic LEDs?
w
Wanelo · seller
You’re paying for dual COB chips, a precision convex lens, aviation‑grade aluminum, and an active cooling fan. When you compare lifespan and performance, cost per hour of safe driving is far lower than cheap alternatives that burn out in months.
