A word of caution here. I think that there is a specific height range for fitting these aftermarket DRL. I'll see if I can find the regulation.
Edit......................
A pair of daytime running lights fitted to a motor vehicle with 4 or more wheels must be fitted with the centre of each light: (a) at least 600mm from the centre of the other light; and (b) not over 510mm from the nearer side of the vehicle;
However, a pair of daytime running lights fitted to a motor vehicle under 1300mm wide may be fitted with the centre of each light not under 400mm from the centre of the other light;
When on, a daytime running light must: (a) show a white or yellow light visible from the front of the vehicle; and (b) not use over 25W; and
Daytime running lights must be wired so they are off when a headlight, other than a headlight being used as a flashing signal, is on.
