	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.

5Excellent Customer Service
My order initially ran into an issue with the Royal Mail international shipping service - Jack from Power Bulbs tracked down the problem and helped remediate the issue.  The package arrived shortly after and in perfect working order.

Thanks Jack and Power Bulbs!

5Perfect choice
2 sets of these were the first thing I bought for my Saab 9-3. They will make a great change aesthetically to your car if it has clear glass lamp units.

5Chrome PY21W
These bulbs work as advertised. With the stock orange bulbs, the orange color was visible through the front clear turn signal lenses. With these Chrome bulbs, they only show orange when flashing, but are invisible when the bulbs are off. They flash just as brightly as the stock orange (non-Chrome) bulbs. Once I placed the order, it took about 10 days to get the bulbs from Powerbulbs.

5Perfect bulbs
Have used Power Bulbs before and would recommend them without hesitation. The bulbs arrived in a very securely packed box and the bulbs were far cheaper than other places such as Halfords.

5best bulbs

4Nice bulb
Very bright.
When off it is invisible at night but a little amber in the day.

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.

5great 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.

GReat product, fantastic service
OSRAM Diadem Chrome PY21W (581) (Twin)
3Ok 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

Great product - looks almost silver and a great amber light.
