OSRAM Diadem Chrome PY21W (581) Indicator Bulbs

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. The OSRAM CHROME DIADEM bulb features a silver coloured surface which will enhance the styling of your car as the indicator bulb will match the chrome of the headlight unit.

So what are the benefits of upgrading your signalling lights? These clever OSRAM DIADEM CHROME 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: if you’ve purchased new headlights it’s worthwhile upgrading your other bulb fittings too.
