While driving the Hume last night my right hand lowbeam light has blown. I do a-lot of night driving and have a pair of lightforce spotties for the open highway but have found that my lowbeams are not up to scratch. Now that one has blown I was wondering if it is worth replacing them with Hella plus 50s or something similar. Any other suggestions would be great. Is it difficult to replace them? (as reading the service manual it seems fairly complicated) and what sort of lights does the XH have?H1,H3,H4? I can't find it in the manual.
