We wondered just how Ring managed to get so much more light out of such a small bulb! With up to 120% more light on the road over & above a standard bulb there is no doubt that you will be seeing a whole lot more in front of you. The other bit of good news is that this bulb is completely strfleet legal so no isss with MOTs when required or Mr Plod. Its just a stralight swop with no need to upgrade any wiring etc. This is plug & play val that really does work!
