I've replaced my interior lighting to LED's recently.
I bought the following conversion set from abroad, but it was missing the bayonet types for the front dome. Below are literally what i purchased to do the whole car including footwell , glove box & boot. Note the 10 piece set-up is missing the bayonet type. I've already fed this back to the seller.
