Test - went to e-rev asked the guy to show me how he wanted to do the lining. Also asked him to insert portion of the led strips into my dashboard and powered up with an external batt... did not take pic... i think if you have black interior, u should be quite safe.... beige interior does not go along with optical lining... at least for my car.
The guy also told me because of the dashboard design, need to glue portion of the lining so that it dont come out... then i told him forget abt it...
