Traffic Light Diawl Bach

The Traffic Light Diawl Bach is a slim, versatile subsurface pattern built around three subtle flashes—red, green, and pearl—that imitate the glint of emerging buzzers, small nymphs, or drowned terrestrials. Its peacock herl body gives off natural shimmer, while the colored ribs mimic the segmented highlights of real pupae rising through the water column. Fished on a slow figure-eight retrieve or allowed to drift naturally, it triggers takes when trout are feeding just below the surface or cruising in stillwaters.

Use the Traffic Light Diawl Bach as the middle dropper in a three-fly setup. The balanced weight and subtle flash make it the perfect “confidence pattern,” often drawing fish in—then getting eaten instead of the point or top fly. Many anglers discover it outperforms the rest of the team on most days.
