Light without render

I have a question. Is there any way to make light in sketchup without render?
Because I am doing cabinet designs. sometimes I have to add led light in the cabinets. To show the light to the client I have to render whole scene using vray. due to render the whole area, I have to add materials to all parts, adjust the environment render and light setting etc.
So I am simply thinking to add light without render. is there any way??
Please forgive me, if it is a stupid question.
Thanks in advance.

Add a gradient texture (White > Transparent).
