Great value Great fit
Great value and a perfect fit for my Mark 7 Fiesta. Love the deep orange colour, they look quite at home in my back light housings. Easy to remove the old ones before then putting these in. The only frustration is having to remove the whole light unit to access the bulb housings, so hope these last a long time!

Great if you need indicator bulbs.
Exactly what it says on the tin. Successfully blink when arm next to steering wheel deployed. Easy to fit. Saved me £20 and a retest on it's MOT.
