Halfords Advanced Premium

These bulbs are so new, they are only just hitting the shelves now. The twin-bulb pack claims a “Premium Upgrade”, but is vague about exactly what that is, only promising an “enhanced light output”.

The KXPR +20 bulbs were pretty inconsistent, although overall the beam wasn’t far behind most of its rivals. Even so, the pack looks good value for money compared to Super Brilliance.
