The DT stick light bar comes in 2/4/6/8 modules with a TIR lens. It has 6 alternative flash patterns and 3 selectable direction patterns. They are the left arrow, right arrow, and center out arrow. It is always in amber color when it is used as a directional light bar.
6 or 8 modules both can be arrow sticks. They will be installed on the back of the vehicle by pairs of brackets for warning and remind people it will go left or right.
Sometimes they can be used as rocker panel lights on the pedals. DT sticks can be in dual or trio colors so we can make it red-blue with white for police to use or all blue in some states in the US. White color means flood mode. When you open the door the stick will be lit at the same time.
When you need a direction warning light that will surely grab the attention of anyone around, the DT sticks will surely do the trick. If any module on the stick got broken, you can easily change it with a new one. It's convenient to repair the light bar.
