The tikli or spangle is worn in the Hindustāni Districts and not in the south. It consists of a small piece of lac over which is smeared vermilion, while above it a piece of mica or thin glass is fixed for ornament. Other adornments may be added, and women from Rājputāna, such as the Mārwāri Banias and Banjāras, wear large spangles set in gold with a border of jewels if they can afford it.

AKA stick on bindis have a bit of a history. Bindi illustrations of 1916 in Pic 1 are quite varied and interesting.
The extract described one method of making bindis/tiklis/tikka before the ubiquitous stick-on glitter bindi packets of today. These tiklis served as a substitute for sindoor or vermilion in marriage ceremonies though both could be used. Pic 1 is from the text and illustrates the kinds of tiklis that could be achieved with the method described, given the lac base I assume these were then stuck on in some manner. Pics 2 and 3 (2 from the1950s and 3 contemporary) are probably made by a similar method or approximate the 1916 tiklis.
