I've found a replacement globe in halogen with the correct base for the Kinlon, an H(S)2 Phillips at 35 watts but as I have plastic 'glass' in the headlamp it will get too hot and melt apparently, from what I have read. Would it be OK to simply drill air holes in the metal headlamp casing or would the cool airflow blow the globe? I don't think rain or splash water will get in if I position the holes right at the top front and at back bottom for air flow - because the plastic shroud should stop that (hopefully). Any thoughts?

As a by the way, a single replacement indicator globe cost me $9.95 locally! Grrrr. Things are quite expensive in Country Australia I think!
