    Rated 4 out of 5 by Misleading colour but better than an egg yolk I bought a pair of these bulbs to change the rear indicators on the rear of my Skoda Octavia VRS 2010. The rear light cluster has the indicator bulb positioned quite clearly behind the clear plastic so inevitably it looks like an egg yolk! This is not the same for the front lights since the bulbs are hidden behind part of the chrome inner plastic. I manage to get a pair (last two left on the shelf!) and replaced the rear indicators. It was quite easy enough on the Octavia as you just open the rear panel and push in the grey/white tabs to pull the light panel out. Twist and remove the old one, push and twist the new one, bosh! I did notice that the bulb is barely silver, unless they have renamed Blue to Silver and forgot to inform the world! You can sort of make out the orange hue of the bulb and if you squint one eye and close the other, you can see a soft silver lining. Once I put the light panel back into the light cluster, I checked the operation of the bulb. Works perfectly! Flashes amber and not a faded yellow like some of the proper chrome bulbs you can find. This will definitely help keep the car road legal, probably more important than being stopped for having faded rear indicator bulbs. One thing I did notice is the blue shade of the bulb does reflect a lot more in the rear cluster, but it actually looks much more appealing that the egg yolk. Its not a solid blue, its a glimmery, pearly blue, you could probably get used to it quite quickly. All in all, a very nice product, easy to install and simply pleased with its performance, I just hope the bulbs' description is advertised more appropriately in the future. I like this range that Halfords stocks, keep them coming! 11 February 2016
    Rated 1 out of 5 by They're not silver, they're blue Described as silver or clear when unlit is not correct. They are blue with no hint of being silver whatsoever. Sold in packaging which has a blue background, I thought it was the blue reflecting off of the packaging. However, you have to break open the packaging to get the bulb out. Hoping they would reflect the silver of the reflector in the car, I fitted them but they are still blue. I've ordered another make online and I am hoping to get a refund for these when I return them. 30 June 2015
