Rear Combination Stop/Tail LEDs T20 Wedge

Hi Folks... just wondered if anyone has been able to find LEDs that fit the T20 wedge connector that act as a combination stop tail light... in white?

I've trolled ebay and aliexpress and asked many sellers to no avail. Either they don't have any idea what I'm after and try to sell me a single "filament" LED. Which acts as a on or off light... not combination. 

The application is for an aftermarket undertail for an RC51 that shines white light down through a slit to illuminate the plate as well as act as a tail light and stop light.

The issue is heat.... the incandescent bulb gets very hot and has started to distort the lens. I thought I would ask here as it's bascally the same setup as the Australian 5thGen tail.

I have picture if needed... just couldn't find much on here regarding the rear lights, moreso headlights or indicators.

Thanks

When I tried white combination led bulbs on my 5G I found the stop light looked white. 

LEDs are a point light, and look white even though the red lens. 

I now have red combination leds and I’m happy with them. 

The number plate is now red, so be it. 

Yeah I wondered how I'd go up here with a red light on the plate.

You wouldn't happen to know which brand/type you went with?

These ones.

I tried the Philips reflector type, but found them too weak.

Thanks for the suggestion OZ... after taking some measurements, they're gonna be too long for the housing 😞
