            Abstract : 
The danger signal advertisement is a unique way of using light to get (secondary) attention thrown over to an advertisement placed along the roadside. Warning those who pass by of approaching danger it fulfills a two-fold purpose by directing attention to the road and creating the tourists´ good will toward the advertiser who erected it.
