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.

Very bright. When off it is invisible at night but a little amber in the day.

4 Diadem Chrome

They aren't true chrome (mirror effect), like the other cheap alternative. You can see inside the bulb from the side but not from the front. They emit a very good light, bought these because I think Osram's are more durable then other cheap brands.

5 great bulbs

the bulbs are a perfect fit. There's absolutely no amber color when light is off. Headlights look great with them.I'm going to buy another pair for my rear turn signals.

3 Ok but not great

Slightly disappointed in these bulbs. I remember having a set ages ago that were great but these ones still appear slightly orange and the chrome finish scratches off easily if you aren't very careful fitting the bulbs (hard on a 1 series!!) I guess it's the price you pay for road legal
