VFLUO - Kit 4 Retro Reflective Stripes Stickers for Mortorcyle Helmet - Stickers Approved to FR Dimension - High Visibility, 3M™ Technology - Discreet and design - Maximum Grip - Set of 2

I bought these because my motorcycle instructor complained that he couldn't see me making my observations in low light thanks to my black helmet. As you can see in the pictures they're discreet in normal light, but pretty bright with a light source pointing at them.(Edit) I've learned with a bit of testing that these are only any good when the light source is coming from the same position and angle they're being viewed from.

Seriously, I just got my fifth set for another new helmet, and I couldn't be happier if I tried.If anybody thinks the stickers can't be seen, they should shoot a picture with the flash. They are in the truest sense of the word brilliant.They don't scatter the light, it's only, but concentrate so, very, very visible from the direction the light is shining on them.One might hardly notice that as onlooker from the side, but the ones who are aiming for you, they see you alright!Again: Brilliant. Can't fault them a bit, so, anything less than five stars, I just don't understand.

These are stuck to a hard black plastic bumper.Firstly, you MUST clean the area with isopropyl alcohol otherwise you're wasting time and money. They are extremely reflective and almost invisible in the daytime. They've survived many jet wash sessions, so preparation is essential.

Easy to apply.

The VLUO black reflective stickers have been on my bicycle for over a year now, and they work perfectly. At first I felt they were a bit on the expensive side, but they are quality and well worth the money.The stickers are black during the day, and after a year they didn't discolour at all. At night time they work perfectly as bright reflectors.I would definitely recommend those stickers if you want a reflector that looks good on black lacquer.

Easy use and well worth it. Would definitely use them again

Wish I’d done some research, these 4 pieces represent very poor value compared to other offers on Amazon. VERY expensive for 4 bits of tape!!

Brilliant reflective strips. Have put them on my motorbike helmet, as well as my motorbike panniers. Wife a lot happier now when riding pillion at night.
