Frequently Asked Questions: OE 15784778-00
Is this the lamp for the left side of my car?
Yes, this is the left hand rear lamp assembly. Left and right on this page are given as seen from the driver's seat looking forward, so standing behind the car reverses what you see. The quickest check is to look at which lamp is damaged while sitting in the car, then order the matching side. The right hand assembly is a separate listing with its own OE number, so do not assume one page serves both sides. If you are unsure, send the number from the old lamp through the enquiry route with your vehicle details.
My old lamp reads UKEA-4133010A. Is this the right listing?
It is. This left hand assembly is sold under OE 15784778-00 and carries UKEA-4133010A as an alternative reference, so either number brings you here. Read the marking with the lamp out of the car and in good light, and take every character rather than the leading block. Make sure the number you are reading came off the side you intend to change, since the two sides do not share a number. If the number matches neither of ours, send it through the enquiry route with your vehicle details before ordering.
How soon does the left tail lamp ship?
Delivery takes 8 to 28 days from your order to your door. Neither is affected by which side you order. Nothing on this listing puts it outside normal handling, so it travels the usual way. Book the fitting once the lamp is with you and not before. If the car has to stay on the road in the meantime, ask your garage what temporary measure is acceptable, because that is a judgement for someone looking at the actual damage.
What is this lamp assembly made of?
Hold it against the car carefully while you compare it with the old unit. Plastic surfaces mark easily, so leave any protective film in place until it is fitted. The listing states no bulb detail and no connector detail, so take that from the vehicle or ask your garage to confirm it before the old lamp comes out.
Why is only one version of this lamp on the page?
Because only the Original/Genuine assembly from BYD is available for OE 15784778-00. No Aftermarket equivalent has been listed for it, so the page carries a single option rather than two tiers side by side. The assembly is supplied new. If you would rather have an alternative, use the enquiry route with your vehicle details and the number off the old lamp, and we will tell you whether anything suitable can be found. Nothing will be substituted for the genuine part without your agreement.
