Ring Xenon HID

Best price: £64.99 Beam: 269.7

We ordered the Ring Xenon HID bulbs for our test through an online retailer, and identical boxes were delivered, but they contained different bulbs. The GE-made burner was clearly the better performer, and if we’d had two of these it would have been our pick of the standard bulbs. Sadly, the Alite bulb in the other box was less effective, and we had trouble connecting it to our BMW test car’s electrical socket, suggesting a build problem. The beams were also different to the eye, with the Alite focus more to the left than the better GE bulb’s.
