I don't think there is anything available to replace them. The only way is to have something manufactured which would cost a fortune. The only way I can think is to have some sort of bulb holder which clips over the led instead of having silicone. Any replacement smd's would still need some minor DIY but it this idea would speed things up.
Will probably get some bulb holders and have a practice on the spare vents I have.
