Dead-beat boarding shabby car - here’s one of its features (8)

'one of its features' is the definition.
I can't judge whether this defines the answer.

'dead-beat boarding shabby car' is the wordplay.
'dead' becomes 'd'.
'beat' becomes 'lam' (I've seen this before).
'boarding' indicates putting letters inside.
'shabby car' becomes 'heap' (heap can mean an old car).
'd'+'lam'='dlam'
'dlam' inserted within 'heap' is 'HEADLAMP'.

'here's' acts as a link.
