*by S***M on 2 May 2025*

These festoon 578 bulbs are a great upgrade—much brighter than the stock ones and they give the interior a cleaner, more modern look. The build quality seems solid right out of the box. I haven’t had any CANBUS errors on my 2008 Freelander 2, which is always a relief with LED swaps. Longevity is still a question mark, but since it’s a multi-pack, I’ve got backups if needed. Overall, a good value and a noticeable improvement.
