Adding side marker/indicators?!

This won't work. The light distribution is all wrong and too dim for the front turn signal function, and those reversing lamp housings take only a single-filament bulb, not the double-filament kind you need for a park/turn lamp.
can you explain the light distribution being wrong? is that based on the bulb? can i use the reverse lights housing and maybe gut the insides and put the double filament bulb and wiring in it? thanks
