If you and your dive partner dive with tank lights, then it will have certainly happened to you before, where you have shone them directly in their face. For example while shooting a buoy. This happens because the beam shines straight forward from the clipped lights. There is a simple but effective solution: a small bungee line attached to the back of the lamp head. Using a double-ended carbine you can then attach the light head to the chest D-ring. The light beam will then shine on the floor below you.
Step 1: Where can the rubber line be attached?
To fasten the line, there are two possibilities. Some lamp manufacturers have a circumferential notch (see picture, right) on the end of the lamp head, with which you can attach the line to. The second option would be to simply tie it onto the back (see picture, left). Below I will explain option number one:
Step 2: Knot the bungee loop
Cut an appropriate length of rubber line for the handle. The length of the line should be chosen so that you can easily attach both ends of the double ended part. This prevents the loop opening unintentionally.
Step 3: Form a loop
Form a loop from the rubber line. Then put it in the location where you want to attach it. Then start to wind the nylon rope around the location of the light head and through the loop two or three times. Tighten the ends of the nylon rope tightly!
Step 4: Knotting the loop
Next, put the nylon rope through the loop once or twice. This helps the construction to have more stability. Should a line tear at any time, which does not affect the whole loop. Then tighten it firmly up again!
Step 5: Set the last knots
Now the nylon rope is knotted well. Trim the ends to about 5mm in length and then melt them with a lighter. Then flatten them (either with the bottom of the lighter or with a screwdriver). This also prevents the accidental opening of the knots.
To temporarily cover up the lamp head you only need a double ended carbine. The result should look like this above water:
