YRV tail light repair

Forum: 

Hi all,
Apologise for my ignorance in asking this question. I have a YRV 4trak and the mrs smashed a rear tail light today.

I called Daihatsu dealer and he said i can buy a replacement lens for £65 or the whole light unit.

I have inspected the damage and all the rear bulbs still work and the plastic is smashed and also some of the silver plastic inside the light.

It looks as if the light themselves stick through holes in the lens so do i just need to buy the lens and fit it over the lights or do i need the whole unit for £110?

Cheers

Adam
