Not too many variations of this bar. There is one with only one amber dome, the other one being all-red except the 2 clears for work/brake lights. Also, consider all-red except work lights or the "police wrecker" style with blue/red and clear work lights.
the 25RWLI2 has a red segment on each end of the rear side because of the stationary light without any filter. The 25RWLI has a special brake light housing.
