I'm replacing the right low beam bulb on my 98 Accord EX V6 sedan for the
first time, which gives rise to two questions:

1) The owner manual says to use a 51 watt HB4 bulb, and that's also stamped
right on the plastic near the bulb on the car itself. But most of the HB4
bulbs I see listed by auto parts dealers are rated at 55 watts, not 51
watts. If I only replace one low beam bulb, will this cause a visible
mismatch in the amount of light from each side? Does it make any difference
whether it's 51 watts or 55 watts? If so, does anyone know the brand name
and dealers for a 51 watt bulb?

2) Behind the left low beam headlight assembly there is a black plastic
shroud attached at the top by two clips which are easy to remove. But the
same shroud is held at the bottom by something I can't see. How do I remove
the shroud without damaging the bottom attachment point? Do I just pull it
up, and pop it back, or is there a clip down there, too, that I have to
retrieve and replace?
