content: Hey all, so for my car I got some wheelen mirror beams, however unfortunately it would be illegal to use them in their current red and blue configuration, and they wouldn't really work as turn signals in those colors anyways.So, luckily they are a package I can replace without an SMD station, however I'm not sure what package these are, and was hoping someone here could point me to the right size so I can order some amber ones.Should be a fun project, I'm going to make two videos, one showing them as is, the disassembly, and strobe functions (they have a solid one which will work perfect for me), and then a second when I actually swap the LED's out.edit: at least I'm hoping I can without destroying the original LED's, not sure if these ones have a heat pad on the bottom that gets soldered.

content: Fuck, the blue one is little tiny SMD LED's, I can't reword these ones, I've never even seen this style before in any videos. Hopefully the guy I got this from can get another older one or something maybe.

content: The big LEDs on the pic apper to be a standard "1W" or "3W" chinese LED, which I think is the same package as the Seoul Semiconductor SSC-P4 (maybehttp://www.aliexpress.com/item/High-Power-LED-Chip-1W-3W-COB-LED-Beads-Lamp-Light-Amber-Epistar-595nm-600nm-for/32631732511.html).The blue LEDs could be CREE XP-E and shouldn't be too hard to rework them either, just brutally hot air them away, wick the pads and apply new solder paste, then gently reflow the new one straight from the top.You can also but pre-mounted on a MCPCB so you could just run two wires from the PCB to the LED mounted on the aluminum substrate (likehttp://www.aliexpress.com/item/10pcs-lot-US-Original-Cree-XPE-XP-E-Amber-Led-520-535nm-on-16mm-Star/32430346616.html).I suggest you to replace both LED style with the same LEDs, or you may end up with different colours and hues that would look awful.

I'm hoping he can find some that are the same as those 1w/3w led's then I can just trade him, because it would be worlds cheaper than buying these things new.Not sure how well I could graft on the bigger LED's to the new one, if it would even work all that well or if they would line up properly. Would also be a bit of a hack job.

Wrap the back end with fiberglass insulation and cloth so you can hold them, heat in flame, remove LEDs.Specific 'difficult soldering jobs' can always be defeated with a little ingenuity. Hope you like the one I just did.https://www.eevblog.com/forum/repair/replacing-a-bastard-dual-sata-connector/
