Bright blue lights feel and look well made neot a bad price it functions the way its been intended to and is sealed well to make it waterproof it has Zero magnet strength as its not ment to be magnetic easy to install with plenty of extra wire apx 20cm of length. With wires already made up for easy install.

For the first time ever they were easy to used l a very good price only issue I had was there was no wiring instruction with them but I did find it on amazon were I order it

One strobe failed after one wke on van not worth the money

Select pattern (touch yellow to black wire) on all lights before syncing (connect white wires together)! Bright, decent quality and easy to install. Added to front grill on Ford transit , work great , thanks

Good little lights which appear well made and easy to install and use. No instructions but the photo on the listing really explains everything you need to know. They’re plenty bright enough and as good as some lights I have which are double the price. Don’t know how long they will last but no concerns at the moment. I bought a pair of these and one light is a slightly different shade of amber which isn’t noticeable in the daylight but you can see it if you look closely at night. My one concern is the foam gasket supplied is not going to be waterproof. This is a concern if you want to mount straight to the bodywork of a van. The cutouts for the wires and screws do not fully enclose them, so water can easily find its way in unless you gunk it up with silicone. Something to be wary of. The synchronisation feature is good and easy to use. Put both lights to the same flash pattern and then connect the white wires. You can then touch all the yellow wires to negative and the flash pattern changes for all lights. The only downside is that all of the lights flash together - you can’t seem to get them to alternate back and forth. You can choose a flash pattern which is half/half of the light to get a similar effect, but otherwise they flash together. Overall, would recommend if you want an affordable light with good bright performance and aren’t mounting to bodywork.

Ordered these for the back end of my concrete mixer, as originals had died or had broken wires. Easy to fit and change the flash mode, just by touching the yellow wire core on the black earth wire core once to change the effect. Happy with brightness too.

No fitting instructions but Easy enough to fit. Plenty of different light patterns to use. Yellow wire contacting the black wire changed the light sequence. White wire for syncing all the lights together works great. Side note as ive seen people say that your stuck on one pattern when syncing the lights. You need to individually select the pattern you want for all lights BEFORE you connect all the lights together with the white wire.

The lights themselves are excellent. Love them. However, the mind boggles as to why they wouldn't come with a switch or detailed instructions 🤷 This is neglectful, hence 4 stars. I bought a separate combi switch with on/off rocker and monetary push button for changing mode. It didn't work at first because the lights need the monetary button to switch to earth (negative -) via the yellow wire, but the button switched to live 🙈. No problem though as the switch was easy to rewire to earth. Now I can scroll through the various modes any time. I would recommend them but only if you know what you're doing with vehicle electrics.

Très qualitatif et super puissant ! Personnellement, j’ai monté les feux à l’intérieur du véhicule afin qu’ils soient visibles de l’extérieur au travers de la lunette arrière et au niveau du 3eme feux stop. J’ai réalisé le branchement sur un interrupteur pour l’alimentation et un bouton impultionnel afin de changer de mode de clignotement .

Luminosi e di buona costruzione. Tutto ok!

Luce spaventosa non riesci a guardarle, dopo mesi di uso una su 4 fatto po' di condensa ma funziona lo stesso ,pari agli strobo polizia .

Bon produit je recommande pour le moment étanche éclair très bien même deux jours À voir dans le temps
