Hi Gardog,
I changed my indicators, several years ago, to combination DRL/indicators using new 1157 (dual contact) units, with amber lenses, from Holden Vintage and Classic in the UK. I hooked into the switched power from the ignition switch to the coil for DRL power. The actual LED insert I used was a flat plate motorcycle product with 42 amber LEDS. The imbedded chipset would recognise the incoming indicator power, when selected, and then the DRL would blink on and off. To fit the flat plate insert into the back of the lens, it required some bench grinding of the resiny mounting material intill it fitted snugly, and then stuck into the lens using a small amount of clear silastic. This arrangement can be found in one of the photos.
I wasn’t entirely happy with this arrangement, so recently I purchased the latest iteration of the product. This can be found in the other photo. The part number from Custom Dynamics, a US company, is GEN-4-AW-1157-T.
This product has 42 amber and 42 white LEDs. I mounted these in the same way as previous, except behind a clear lens. This product is on, super bright white, as a DRL, but with an incoming indicator signal, the 42 white LEDs turn off, and the 42 amber LEDs blink. There is no need for relays.
They look just like your second photo. I am hoping that the bright white light makes me more noticeable to other road users, especially the huge SUVs getting around theses days.
Cheers,
Colin

Switched the standard 1157 bulbs for 2" LEDs, changed the lenses to clear and added a timer delay relay (from timers shop) to switch the running lights off when the turn signals come on. I am very happy with the result. The car is much more visible during the day without having to pop up the headlights.
