Illumination needed

[Evelix]

I've had no trouble finding T-5 LED bulbs for the smaller 'twistlock' instrument panel display lamps - but no luck with the larger ones. I've seen these referred to as T-10s but the only ones I can find don't appear to have the twistlock mount - they're offered as just bare bulbs with tails. Can anyone please point me to what exactly I should be looking for? (Apart from a Toyota dealership, that is...)

By trawling around the web I think I've answered my own question: t seems that both T-5s and T-10s are capless bulbs but while T-5s are usually sold c/w the twistlock cap, T-10s are usually sold bare. Unless you know differently?...
