I replaced the left headlight on the Valiant. Since the right headlight is also likely to fail soon, I bought a second unit for the right side as well, which, however, I have not installed. For two reasons: 1) to check the alignment of the left headlight this evening. In fact both right and left lights seem to me unduly high; I need your opinion about this. 2) installing the unit was in fact quite a production, and I thought it might be worth your while to install the right one yourself, or at least watch me do it, in case you should ever have to do it yourself. Margaret and I are about to take a quick trip to Deck House in Acton (1:06 p.m. now). As soon as I get back I expect to start putting another coat of plaster on the kitchen ceiling.
