I have a Citroen relay2.2Hdi L2 2008 both reversing lights do not work and the off side rear light indicator does not operate correctly and light is dimmer than the near side, I purchased some new rear light units as the bulb boards are very rusty but the electrical connection is different, the old light unit has a square fitting with all the terminals in a straight row, where as the new has more rounded square with two staggered rows on pins, is there an adaptor or conversion connector that I can purchase, Can any one help please!
