No not that I know of,although there are lights that can be accessed through the FMB.These lights can be manipulated to raise and lower them,they can be made to look like the lights on a vehicle as long as it is a stationary vehicle and does not move.
To raise or lower objects (lights, fire and smoke are the only obejcts that can be raised or lowered like this)
Place the object on the map. To do this Left click the mouse and press Ctrl
Then select the object by Left clicking the mouse and then go into 3D mode by Pressing Enter while zoomed in close enough to see terrain details on the map.
Hold left click and press F4 and if you don't do it in that order the next function will not work!
While holding the left mouse button move mouse away from you to raise, pull mouse towards you to lower the object.
To move object on the horizontal release F4, hold down the left mouse button and move your mouse
Easy
Edit> Pressing F1 will slow down the response to moving the object so as you have better control over it.Also you can click on the light object if on the map and by holding down both left and right mouse buttons and then pressing F4 while in 3D view you will be able to raise and lower the object.
