The ultimate upgrade and period correct for our classic Opel's! OEM style sealed beams are quite dim compared to these. These have rounded faces that look pretty cool and project a very nice illumination pattern. Once you move to H-4 headlights, you will never go back to the old sealed beams. Set of two (2). Fits GT, Ascona/1900 and Kadett. NOTE: These are for LEFT HAND DRIVE roads like the USA, Mainland Europe etc.. Not for RH drive roads like Japan, Great Britain etc..
