Can't figure out what part this is. Plastic slide-in T-like part measures about 3/16". Bulb is about 3/8".

Thanks so much for reaching out to us. Based on your description, I think our 48-183 may be a good fit. The bulb is 3/8" and the T slot is 3/16", same as your original. Look it over and let me know if you had any questions.
