SINGLE FILAMENT: 34903-SF1-A01
DUAL FILAMENT: 34906-SL0-A01
On my 80 FI the (qty 2) dual filaments are for the front bumper turn signals, the (qty 6) single filaments are for the rear lights, 3 per each module.
(Note that Daniel Stern sells the brighter side marker bulbs (2 front, 2 rear) and I had already installed them. He doesn't sell the Honda bulbs for the front bumper turn signals or the rear modules).
Here are some videos of the result, you can judge for yourselves if it is worth the cost for safety improvement. The bulbs are roughly $7.75 each

This little wire brush is a really good tool for cleaning out the sockets, and I bent the retention tabs in a little to make the bulbs sit more tightly in the socket.
