Doubtful any such thing as 10W led turn signal bulbs
You have to view LED lamp specs with extreme caution - like when LED headlamps are rated at 85W or so - it does not mean they really consume 85W, but that they are supposedly some kind of 'equivalency' (in light output) to (some 'nominal') incandescent rated at 85W (while actually consuming considerably less - maybe 35W)
An LED bulb for a turn signal is probably going to consume somewhere in the 2W range
The challenge with LEDs in the OEM turn signal housing is finding one with adequate output that is not physically too big to fit.
e.g. -
67 LED Bulb w/ Focusing Lens - 3 High Power LED - BA15S Retrofit | LED Brake Light, Turn Light and Tail Light Bulbs | LED Car Light Bulbs | Super Bright LEDs
Note that is says "comparable wattage" = 10-15W; then actual current (for amber) is 240mA
240mA is <3W (nominal)
Incidentally I have seen the turn signal bulbs listed here on forum as both 1156 and BAU15S - these are not the same. Now I can't tell you with 100% certainty
WHICH is used - don't have one and have not removed OEM to check;
but my understanding is that these OEM are actually 7507 which is same as BAU15S;
but the way to tell is to look at the base of the OEM bulb and inspect the locating pins; 1156 have them directly at 180 degrees to each other; on a BAU15S (or 7507), they are offset (150 deg)
You can modify to fit each into the other housing if you trim or grind off ONE of the two pins. (1156 are much more commonly available)
Also important to note that when fitting LED bulbs, often the fixtures' wires have been polarized incorrectly - this is irrelevant for incandescent but becomes issue for LED; if you install LED and it does not light, you probably have to swap the wires polarity.
