They are not black the stickers are a brownish yellow constantly. They do not change colors like advertised.

Would not use on anything for visibility or reflective quality very poor. Bought to put on helmet but used on my driveway entry gate and they hardly show up with headlights shining on them. What reflection there is, is more pail gold not safety yellow.

This was a great addition to my Morning Pride traditional helmet.

Great high visibility product definitely what I wanted.

I wish they had legit black out tets because thats what they advertised and thats not what i was given the color looks gold except at night. The reflectors are not that powerful. Over all pretty disappointed

Out of three different color variations, the blue seemed to reflect better than the orange/silver and yellow/silver combinations (Product Code: W-HT-071O). It's a novel idea but don't expect them to perform as well as standard reflective stickers.
