I added headlights to my Troybilt snowblower and thought it would be helpful to have lights shining down where I’m walking. I made this 90-degree bracket to hold the “Ricoy 3/4” Round LED Underbody Rock Front Rear Side Marker Indicators Light Waterproof 12V for Car Truck Trailer ATV Boat Light, Pack of 10 (white)” (purchased from Amazon).

The holes should align with a hole on each side of the metal frame near the crossbar, so a rivet can be used (the piece should be big enough to reach both the top and bottom edges of the bar, so only one fastener is needed, but two are included for symmetry or to attach it to other locations).
