I have a new (never installed) set of Menosabe made brackets. I understand these allow for either lights or highway pegs since they don't have the extra tab. If I were serious though I believe I could adapt them to fit both lights and highway pegs.

However, since I sold the bike I don't need these brackets that I never got around to installing.

The installation video can be seen on Youtube


A clear picture of the brackets I have can be seen at 6:03 in the video.
