Re-ferrin(, to the drawings, aii ,tutoinobile lieadlight is disc'Losed haa-ing the shel'L or 6 tl-iereori ivl-iieh et,.sin g 5 ",itli the fr iit i@im 60 is arranged to hold in place tl-,e glass or leii-@ @T. This Yiass is lield against an Iililular iiiemb er 8 seated iii ,t groove formed in the iiiaiii refle,-tor 9 which is disposed ,vithin the casing 5.

TI-ie sleeve 12 pi@eferibly is split Lilong one si 'de as slionvn at 12" and said spllit is colitinlied tlirougli the portio,,i 12c of the rei4ee- 85 tor for i sh-ort distance. A leaf spriiig 13 is shown -,Ls seciirecl at oiie en(I to tl-ie rear of tlio reflector 12 and extend,; toivai-d the end of sleeve 12,1, the eiicl of saicl spl-iiig beiiig bent, ts slioivn at 13@ to pi,oiect across 90 the iear end of sleeve 12a ai-id slightly into the pass,,-lge therethrougl-i. Tt Nvill be noted that the reflector 12 is formed with a portion 12b at one side of sleeve 12a on a COMp,,)rqti vely fl,,,t clirve, tlle sicles of the re- 95 fiector meeting in a poiiit. The reflector is foriiie,- l with its o@tl-ier side 12c@ of much sliorter length tl-ian the length of the portion 12b and the portion 12C is formed on t sliarper cur-ve or a etirve @,@ith a smaller 100 PartieLi";ar i-aditis tliftii is the portioii 12b. attenti oi-i is called to the fact that the line tancren t to the center of the port-i-on 12L makes aii angle of stibst,,intia;lly fortv five cleuree s Avi.Vii tl-le axis of the sleeve l@a ancl 105 that the line tangent to the ceiiter of the

AVith said poi-tions so disposed, @l the reflector 12 ca@,ts a (yood at the si(-Ie zn of the iuachine about ten feet aliead of the automobi'e, as sho-wn by tests made on the -well kno-wn Forcl alitomobil-e. The e:ff--ct would be substantially the same - with other makes of cai-s. Tlie portion 12' lias the im10 poi-tant functioli of preventing a sliadoiv at the front of the rqachii-ie.

The eiicl 13,1 oi the spring 13 is raised so thilt it pi-esses doivn on the lai-np socket 10, the eiid of said spring being curved slibstantially -ivitli the sa,-iie curvattire as said socl@et. The reflector 19- cin 20 lio,,v be rotated on lamp socket 10 and yet will @remain il'i its adjti--ted posi@,ioii thereon. TI-ic sleeve 12a beiiio- ,pliL is somewhat resilient alid can tiglitly eiigac)-o tl)e lainp socl,-et 10.
