Hi all, I recently went to change a bulb in one of our marker lights as displayed below, only to find that the rear of the unit had melted to the bulb holder. Shocked I did phone their parts department at Broonfools of Newark to make an enquiry, but knowing their reputation and that I wouldn't get much joy from them, I managed to source the marker lights from http://www.titgemeyer.de/index.php?id=614&L=7 In the time that Broonfools took "not" to return my call with the relevant information, 2 x marker lights were sourced, ordered, and delivered from Germany (before payment received), courtesy of Andy Washington at Titgemeyer UK, for less than £15 inclusive of VAT and standard postage. Unlike the old marker lights, the new ones have a rubber boot which protects the electrics from the elements. Regards to all. Jock.
