Okay, this is a search link for the Philips Line of LED bulbs. They are direct replacement for both the 1156 and 1157 filament versions. They also come colored, meaning that even though they appear clear, when lit, they show as a color, red, amber, blue, etc. The product codes will appear as 84175 and 84176 base numbers with a letter suffix to denote the color but they are, de facto, the old p/n's.
I just changed out the stock bulbs in my G-10 Van for a set of these; 1156 and 1157 in the rear tail lights and 1157 in the front units. The plan now is to revisit the fronts and sub in a pair of 1157a's. That gives me amber front turn signals in case the clear units are no longer legal. As for the side marker lights, you ought to be able to tweak the link to make them appear.
All mine came from a Canadian!! supplier but this link ought to show US sources.
The only abberation that I have encountered with them, and with the Osram/Sylvania's before them, is that, if you turn the key to on, and then pull the headlight switch, you get solid blinker lights on the dash. With the headlights on, they will not blink until the engine is running??? Then they do blink correctly but, when shut off again, go back to being a solid light. They do go out as they should when the light switch is turned off and the engine is shut off; no headlights and they work as the factory intended. This might be a blinker switch issue but doesn't seem to be a short so I am living with it until rotation day when i can bring the van back in and start repairing all the insults it has endured this summer.
