[p5b401]

401 using standard rear indicator assy with clear lens. Mine has two lamp sockets with lamp areas largely separated by a metal shield - I assume that is standard.
I'm using high intensity amber indicator LEDs in the forward socket and standard red LED Brake/sides in the rearward socket.
To further emphasise the rear turn signal have made the following circuit. which operates each side of the rear lights independently without affecting any other light on the car:
If the brake light is on the circuit cuts power to the brake light leaving rear side light on while the indicator is flashing.
If the brake lights are not on then the circuit does not operate.
As far as the front lights are concerned, I had to install new driving lights so I opted to install a new sidelights (Lucas L488). These are round with a chrome bezel and clear slightly domed lens. I have fitted them below and roughly central between the head and driving light on each side.
Just another option
