On the wheel balancers one laser pointer indicates the exact point to fix the weight on the wheel rim to the operator.
The red line LS12 series laser pointer, supplied at 5 Vdc and with a power of 3mW, is perfect in this case; consult the data sheet at this link: https://www.smprox.it/en/product/sm306005/
On request it is possible to focus the line at the desired distance.
