Oval 60mm x 38mm. Replacement part for Ford Fiesta 94 on and Mondeo 96 on. With a slight modification it may be fitted to most cars and would require a 20mm hole. If modified the retaining clip would have to be cut off and the unit held in place by the self adhesive double sided gasket supplied. This unit is not “E” marked. Requires holder and bulb such as CL0523 Each
