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.
Smart-Flash Enabled
LED indicator bulbs will get very hot if they are on for a few minutes. This causes LED bulbs to fail prematurely.
This is usually from prolonged use such as when you're stuck on a lay-by or broken down.
How It Works
Twenty20 has a built in system to prevent the bulbs from reaching a maximum temperature.
This causes the bulb to produce a dimmer light which is still bright until they have cooled down. Once they have cooled down, the light output goes back to normal.
The Smart-Flash feature prevents the bulbs from failing early, extending their lifespan beyond other LED indicator bulbs.
No other LED indicator bulbs that we supply have this feature making them a very unique product right now.
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.

Quick and easy delivery, great price.
For a Focus Titanium HID light unit, the bulb was a little big. So took some figuring out but once in and fitted, massive improvement.
Advantages: - Bright for sure
- That clear sharp on and off of a modern LED indicator unit
- Won't flake off like a conventional filament bulb.
- No Hyper flash like advertised
Disadvantages: Probably a bit too bright to fit to the rear indicators, dazzling drivers behind.

I purchased these for a Renault Kangoo MK2 for use at the front where the indicator is built into the headlamp unit.
When driving with the headlamps on the standard indicator bulb tends to be drowned out by the glare of the headlamp. With these LED bulbs installed the indicator is much brighter and is still clearly visible when the headlamps are on.
Advantages: Very bright and fit into the standard bulb space. Good amber colour. No hyper flash, the standard flash rate is preserved. Hopefully a longer life, time will tell.
Disadvantages: Too bright to install at the rear, the light output from these is similar to the flashing LEDs used on recovery vehicles. They will annoy people close behind due to the intense brightness.

Mainly I am happy with this bulb lights.
Advantages: It is a LED bulb, it look way more nice than a normal bulb light.
Disadvantages: Brightness of LED bulb is a bit too high for my taste. I think brightness is a bit discomforting for driver behind me.
I will look for my next LED bulb light to be less bright.

Very bright turn signals, no hyper flash. They seem quality made, and the installation is practically plug and play (keep in mind to do the coding if required)
Advantages: Very bright (perhaps even too strong at night)
Direct replacement for regular bulb
Disadvantages: As most of the LEDs state, for off-road use only: you may want to check if you will pass MOT with them installed

After almost giving up on LED indicators that hyperflashed or gave warnings on dash, i came accross these.
Very, very bright and they work perfectly.
Needed them both front and back to stop warning messages.
Fantastic service from ABD and very helpful on phone to resolve my queries.
100% recommended - Thank you
Advantages: Very bright and they actually work with no error messages or hyperflash as advertised.
Disadvantages: Large size, may need a bit of encouragement into holder.
More expensive than others but worth every penny.

I fitted these all round to my 2008 Renault Trafic. I have had to go back to original bulbs as these were too bright on the rear of the vehicle, (because of the height of the light fittings). The front ones can stay. My plan is to order another pair fit them to my Yaris.
Advantages: Far, far brighter than any other LEDs that I have bought from elsewhere.
They work straight out of the box.
Well worth the extra cost.
Disadvantages: They are not cheap, but you get what you pay for.

Be aware these are very slightly larger than standard bulbs. A great upgrade, but so it should be as these are certainly not cheap. I fitted them to my motorcycle indicators, certainly brighter than a conventional bulb and a good strong colour. Yes, they blink at the correct rate, so as promoted these work fine with a standard flasher relay. On a bike the indicator housings can be quite tight and these bulbs only just fit in by a few mm, and that's with adjustment to the metal reflector (pliers did the trick there).
So great, I'm very happy with them, but if you have a tight housing for your indicators, you'll need to check that they will fit inside ok.
Advantages: Straight replacement, no flasher relay change. Bright, orange light. Should last a very long time.
Disadvantages: Expensive. Just slightly bigger than a standard bulb, so might not fit inside if the indicator housing is quite tight

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.

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
