Why buy me?


Not only can you upgrade your headlight bulbs, you can also upgrade your signalling bulbs too. The OSRAM Diadem range offers a series of bulbs that can be easily used instead of conventional amber signal lights.

What are the benefits of upgrading your signalling lights? Well, to start with, these clever OSRAM DIADEM upgrade bulbs will last twice as long in comparison to standard bulbs. The main selling point, however, is the enhanced style these bulbs offer. The OSRAM Diadem PY21W bulbs can be used for both your front and rear indicators.  If you’re keen to invest in lighting to improve the overall aesthetics of your vehicle, we highly recommend these DIADEM signalling bulbs. After all, if you’ve purchased new headlights it’s worthwhile upgrading your other bulb fittings too.

OSRAM Diadem PY21W 581 Styling Indicator Bulbs (Twin Blister)

4 Nice upgrade

Bluish amber colour spectrum and more orange amber shade when on. It really is like an oyster. Complements well if you already have blue tinted bulbs in the front. If you want less stand out maybe the Diadem Chrome might suit better.

5 Ooh! Shiny.

Do what they're supposed to, while looking a lovely silvery blue behind the lens. Much better than the horrible yellow ones.

5 Excellent product

I bought the osram diadem Py21w 581 indicator bulbs to get rid of the 'egg yolk' appearance of the indicator bulbs on my wife's black Fabia vRS. The blue tint when they are off compliments the cars colour, yet the function well Asa. Normal indicator bulb when on. Highly recommended.
