The latest 581 LED bulbs fresh out of the Twenty20 labs designed to eliminate hyper-flashing!
Twenty20 designs and builds innovative LED car bulbs for road users that are paving the way for future technologies.
This time around, they've produced a super bright 581 LED bulb that is not only covered by a 3 year guarantee but also contains brand new technology that removes hyper-flashing.
What Is Hyper-Flashing?
Hyper-flashing or "rapid flashing" occurs when you change the technology for your car bulbs from halogen to LED. This is because LED bulbs use less power than standard halogen bulbs and this causes a drop in the circuit's resistance. When this happens, your bulbs will appear to flash really fast hence the name "hyper-flashing".
It's very frustrating when this happens and can cause drivers to panic.
How To Solve Hyper-Flashing?
Before this technology came around there was a very simple solution that most drivers used because it's classed as a "sure fix".
The best way to combat hyper-flashing is to buy an LED resistor kit where you put between the positive and negative wire of the LED bulb, creating a bridge between that raises the load for the entire circuit.
No More LED Resistors Required!
The time for "tapping wires" to fix your hyper-flashing LED's is well and truly over!
Twenty20 has implemented technology that's not only CAN-bus compatible but instead the 581 LED bulbs eliminate hyper-flashing all together.
Super Bright LED 581 Car Bulbs
Not only are these indicator bulbs resistant to hyper flashing but they also produce up to 1,800 lumens.
The amount of light produced is more than double that of other LEDs in the market.

This new indicator LED BULB prevented hyper flash issues on Renault Scenic 2018 without having to install 5w risistors into the wiring. Tried standard indicator LED bulbs which suffered with hyper flash issues.
Advantages: Brighter and quick to install.
Disadvantages: None

Very bright, the best amber led, I have ever purchased in terms of quality & brightness. No errors on dash (Mercedes SLK R171) Forget the ones on that well known site on the bay. (Ive bought loads, which simply does not compare)
Advantages: Very bright,
Disadvantages: None, however I have heard some BMW's, (not all) can show error on dash (bulb out)

The bulbs are nice but they are a little bit too bright to be blinding the oncoming cars and people. They are canbus supported but did not work on my bmw e88 convertible and it kept giving me bulb out warning on the dash unfortunately as it was being extra sensitive. However, the customer service was very efficient with dealing with the issue and offered a full refund.
Advantages: Leds are pretty good overall.
Easy to replace.
Disadvantages: Might not work with some canbus systems.

Well the devices arrived OK but I cant used them as they are too bright, must be at least 6 times the legal limit for indicator lamps.
Advantages: Very bright
Disadvantages: Far too bright for road use and will annoy any driver who is behind you. Novel way of ensuring correct load to prevent hyper flash so you wont get that.

Advantages: Extremely Bright and well built.
Disadvantages: Not compatible with a Saab 93 2010.
Gets quite hot due to the inbuilt resistor.

Recently purchased a pair of 581 Twenty20 HF0 LED Indicator Bulbs as these were advertised to stop hyper-flashing! I am glad to say they definitely do just that. Previously bought the Cree LED's which were not suitable for my Renault Megane F1 Cup, those created mental hyper-flashing! ABD were happy to accept back for a full refund. The New 581 indicators advise up to 1,800 Lumens of light, I can certainly agree with that, they are super bright, probably see them on from the moon! I have all Twenty20 LED lights on rear of my car and passed MOT recently, no problems at all. Test centre advised, LED's are only a problem when fitted to front lights, always check Techy Stuff, ABD clearly show if their bulbs and LEDS are Road Legal or for Off Road use. I have Twenty20 Endurance Halogen bulbs on front and LED's on rear, all work fine, no errors and ABD offer amazing long warranties in this range, win, win.
Advantages: Amazing so bright no hyper-flashing! Or errors appearing.
ABD should apply this technology to all LEDs, saves time spending additional money on resistors, for the price I don't believe they are expensive, they do the job and worth it, 10/10
Disadvantages: None, no need for additional resistors, just remove old standard bulbs and install New LED 581's
