   Suffixes that denote specific versions of the part (e.g. LM305 vs. LM305A) are not shown in this list. Obsolete 4-bit microprocessors of the LM6400 family, manufactured by Sanyo, [97] have no relationship to the analog LM series and are not included in this list. The first digit of each part denote different temperature ranges.

   en.wikipedia.org/wiki/Bi-pin_lamp_base

   The suffix after the G indicates the pin spread; the G dates to the use of Glass for the original bulbs. GU usually also indicates that the lamp provides a mechanism for physical support by the luminaire: in some cases, each pin has a short section of larger diameter at the end (sometimes described as a "peg" rather than a "pin" [2]); the socket allows the bulb to lock into place by twisting ...

Other automotive lighting applications such as auxiliary lamps or interior lighting may not be regulated, but common types are used by many automotive manufacturers.

7. Incandescent light bulb - Wikipedia

   en.wikipedia.org/wiki/Incandescent_light_bulb

   Lamp bases may be secured to the bulb with a cement, or by mechanical crimping to indentations molded into the glass bulb. Lamps intended for use in optical systems have bases with alignment features so that the filament is positioned accurately within the optical system. A screw-base lamp may have a random orientation of the filament when the ...
