Neat little units, great value, work well when used correctly- See my comments
Work well, but please bear in mind that some level of current draw is required to keep the flashing of the LED's regular. These units are possibly designed to have a filament dash indicator lamp in addition to the LED main lamp? I connected a single LED indicator lamp to the product and the flashing was irregular. To resolve this I added a100ohm, 2 Watt resistor in parallel with the LED lamp to ground. Now functioning correctly and an excellent result and remarkably good value too.

Works well with 2 or 4 led indicators
Good value and work ok. I bought these for indicators on an e-trike one for left side and one for right side but when connected to the supply to the left and right latching push switches it flashes at the same speed when just one side is operated or both side at the same time so allows both switches to be operated to work as hazard lights.

Decent flasher module
Can't fault it. It does the job and the flash interval can be adjusted. Just note that while it will technically work with LED lights it will not fix the flash period on LED lights. At least it didn't do so for me. So if that's what you are looking for get a load resistor instead.

GREAT
Used on 1986 Honda MTX80 as 40 year old original had given up. It works a treat and the speed of the indication can be adjusted. FANTASTIC

Worked perfectly
Worked perfectly great product good quality, very easy to install flash rate seems perfect too.

They work for me
They work on a bulb set of indicators. I have not had the opportunity to try them on led indicators as yet.

Work OK but you'll need a resistor to slow the flashing for LEDs
I used these with some new LED turn signals and found I had to add resistors across the LEDS to slow the flashing down. Not a problem as I was making a thing from scratch but maybe not the best if you need a drop in replacement and don't want to faff around.

Not just for motorcycles!
Very pleased, great value for two units. At first I was sceptical, as I was purchasing these for my 1952 MGB, which has a habit of blowing the Chinese copie, sold as genuine Lucas brand, which they are not! The original unit lasted over 50yrs, and the modern copies are lucky to last 6 months! With being listed as for motorcycles I was not expecting them to work on a car's system, yet to my surprise and delight they are perfect! The built in adjustment means they can be altered to flash at your chosen rate. It's early days, yet I now have working indicators again, plus a spare unit in the glovebox should it be needed.

Fungerar inte med led, man måste koppla in motstånd ändå. Ska du köpa ett relä till led, köp ett lastoberoende relä.

Installed these in a motorcycle to get rid I’ve hyper-flash from led turn signals. They have held up good and worked as expected out of the box. Easy install. Adjustable flash speed is a nice feature.

★★★★☆ – Zuverlässiges Blinkrelais für LED-Blinker mit einfacher Einstellung Das QWORK elektronische Blinkrelais ist eine sehr praktische Lösung, wenn nach dem Umbau auf LED-Blinker die Blinkfrequenz nicht mehr stimmt. Das Relais erfüllt seinen Zweck zuverlässig und sorgt für eine gleichmäßige, saubere Blinkfrequenz, ohne Flackern oder Fehlfunktionen. Der Einbau ist unkompliziert, besonders bei Fahrzeugen mit 2-Pin-Anschluss. Stecker aufstecken, Relais befestigen – schon ist das System einsatzbereit. Positiv ist, dass keine zusätzlichen Widerstände notwendig sind, was den Umbau deutlich vereinfacht und sauberer macht. Die einstellbare Blinkgeschwindigkeit ist ein großer Vorteil. Mit wenigen Handgriffen lässt sich die Frequenz genau anpassen, sodass sie sowohl optisch angenehm als auch straßenverkehrstauglich ist. Das Relais arbeitet dabei stabil und ohne Aussetzer. Die Verarbeitung macht einen soliden Eindruck, das Gehäuse wirkt ausreichend robust für den Einsatz am Motorrad. Auch bei längerer Nutzung bleibt die Funktion zuverlässig. Für LED-Umbauten ist dieses Relais eine preiswerte und funktionale Lösung, die genau das tut, was sie soll. Die Lieferung erfolgte zügig und das Relais kam sicher verpackt an.
