Turn signals blink fast after LED?
That is hyper flash. LEDs draw much less current than halogen bulbs, so the car thinks a bulb is out and blinks double-speed. Fix it with a 50W 6Ω load resistor wired in parallel with each LED turn bulb, or an LED-compatible flasher relay.
What drivers say
Nice LED incandescent replacement. Plug and play, replaced all the lights in my RV with LED. Nice as the incandescent generated heat, lights a nicer tone too. Whiter light which I prefer.
Met expectations. Product works as it should, easily replaced the halogen bulb in my Harley Davidson brake light.
Exactly what they are advertised to be. I was amazed at the brightness of the bulb. It slipped right into the original holder and has worked like a charm. We have only been using occasionally for a month or so, since they replaced the interior lights for a 1999 Jeep TJ. But for the cost, even if we get a few years of operation from them, they will be worth the money.
Fast shipping. Great product!. They work great and the best part is you don’t get the fast blinking. (No need for resistors) Plug and play easy to install, really bright!
Purchasing these would be a BRIGHT idea. East to install, fit just like OE lights but much much brighter. These replaced my OE halogen dog lamps and made a world of difference. Bluish/white light illuminates the roadways very well. They look and feel like they're built very well.
Perfect quality. Put these on my marker lights on my Silverado and they were perfect, bright and long lasting, never went out since I got them

Converting an RV to LED bulbsAbout Antline LED bulbs
LED bulbs for brake, tail and reverse lights
The most common LED upgrade is the rear of the car. Antline 3157 LED bulbs, 7443 LED bulbs, 1157 and 1156 bulbs use 21 to 33 high-power chips and reach 1000 to 1260 lumens per bulb, far brighter than halogen. Red versions make brake lights snap on instantly, white versions turn a dim reverse light into a real work light, and 12–24V bulbs fit trucks and trailers too.
Interior, dash and RV bulbs
Inside the cabin, 194 / T10 LED bulbs, festoon bulbs from 29 to 41 mm, BA9S and T5 bulbs replace yellow halogens in dome, map, vanity, trunk, gauge and switch lights, most of them CAN-bus error free. For RVs and campers, 20-packs of 1156 and 194 LED bulbs relight the whole interior and use a fraction of the battery.
Fog lights, DRLs and plate lights
Antline fog light bulbs in 881, 880, H1, H3 and H7 bases add bright white or golden-yellow light for fog lights and daytime running lights — not for headlight high or low beams. Direct-fit LED license plate lights for Silverado, Sierra and GM SUVs finish the rear of a truck.
Bulb questions
How do I find my bulb number?
It is printed on the base of the old bulb and listed in the owner's manual under bulb specifications. Many auto parts sites also list it by year, make and model.
Why does my LED not light up?
Wedge bulbs like 194 and 921 are polarity-sensitive. Pull the bulb, turn it 180° and push it back in.
Why do my turn signals blink fast after fitting LEDs?
LEDs draw less current, which triggers hyper flash. Add a 50W 6Ω load resistor per bulb or an LED flasher relay.
Can I use fog light bulbs as headlights?
No. Antline fog and DRL bulbs are for fog lights and daytime running lights only, not high or low beams.
Do LED bulbs work on 24V trucks?
Bulbs marked 12–24V work on both; RV 20-packs are for 12V systems.
Where do I order, return or claim a warranty?
Orders, returns and warranty claims go through the store where you buy. For help finding a bulb, write to contact@antline.pages.dev.
