hi i get mine of ebay £4.45 delivered
from edjwilson he has nearly 70,000 positive 100% feedback
bulbs are xenon h4 bulb 55w/60 looks blue when off and a very white light on
i have never been flashed by passing motors and they make a big improvement
i also check and clean the the connector with emery cloth and tighten the female connectors and whack a blob of vasaline in them and reconnect
